Cab1.cab Corrupt

[Nikita Desjardins]

Itried to install Visual Studio 2012 . but it showing me "Unable to locate package source" I can select "Download from the internet" or "Provide a location to search for the packages" And this is path that comes up:

(the 'packages' folder does not exists) When I select to download from the internet its showing up again after some time, I searched for "vcRuntimeDebug_amd64" folder but it doesn't contain "cab1.cab" file ;/

I had the same problem but with Windows Phone 8 SDK. I tried several things (which are detailed below, in my previous answer), and the best option was to download the ISO, found in the Install Instructions section:

After finishing, it said it couldn't download that runtime, but at least the emulator is running fine. I guess you could manually download that runtimeafterwards if you have any problems. Here's the link:

I downloaded the Visual C++ Redistributable for Visual Studio 2012 Update 4 to see if that way the installer skipped that step, but it didn't work.Then I looked for cab1.cab in my disk and found it in several folders, being this one the one that worked:

Inside that folder was not only the cab1.cab but also a vc_runtimeMinimum_x64.msi file. When I told the installer to use that folder, it still didn't work. Then I chose "Browse" but when I opened that folder it didn't show any file because the installer was looking for vcRuntimeMinimum_x64 (without the underscore). I typed "." in the textbox so it showed all the files, I chose vc_runtimeMinimum_x64.msi and the installation continued. It took a while but it worked.

File corruption, missing, or deleted cab1.cab files can result in MSDN Disc 5267 errors. Ordinarily, installing a new version of the CAB file will repair the problem creating the error. We also recommend running a registry scan to clean up any invalid cab1.cab references which could be cause of the error.

Placing this new cab1.cab file in the same location (overwriting the previous) and your issue should be resolved, but you'll want to check to be sure. Re-open and test MSDN Disc 5267 to see if the issue has been successfully solved.

Some time ago I blogged that you should try copying the installation locally as in some cases this is related to brief network disconnects or disc read lag, or even a bad burn of an ISO image. You should still try that and other methods in some of the comments on that post first since those are for more likely problems.

If you do not have Internet access, or have a restrictive firewall or proxy, setup may be failing to verify the signature because it cannot access the online certificate revocation list (CRL). This is most likely if you encounter the error on cab1.cab for VS2008 or MSDN.

If you still cannot install VS2008 or MSDN with the same error 1330, make sure that option 9 is set to its default value of FALSE. If this option is TRUE, then the timestamp server is queried for a CRL as well and will fail under the same conditions.

During installation, Windows Installer calls WinVerifyTrust() to verify that a signed file is valid. By default, a certificate revocation list (CRL) is downloaded and queried to determine if that certificate has been revoked. For VS2008, that CRL is located at If an Internet connection is unavailable, WinVerifyTrust() cannot download the CRL.

A similar problem may happen if option 9 is set to TRUE, which tells WinVerifyTrust() to check a CRL on the timestamp server if the signature is timestamped. The error returned is different, however: 0x80096005, which is TRUST_E_TIME_STAMP.

i am connected with a mobile stick in my holidays - the connection is quicker as my DSL at home, but i downloaded the package twice with the same corruption error. I will not try any more. To test and to know that it is corrupted has no use at all because I have to download the WHOLE package again. It is a poor technique, you should have any downloader which is able to handle great files with fragile connections.

:-(((

I am trying to install FME Desktop. And I am getting a which reads, "The cabinet file cab7.cab required for the installation is corrupt and cannot be used. This could indicate a network error, an error reading the cD-ROM or a problem with the package". Could anybody please help me on this?

Sorry to hear that you've run into this issue with your install. Would you be able to try reinstalling FME Desktop to see if that may resolve the issue? There's an article here that might be helpful for that.

In addition to what @jovitaatsafe said I would also recommend downloading the installer again, in case the download file has gotten corrupted somehow. It hasn't happened to me in a long time but there have been cases in the past where an installer got corrupted during the download.

[1]Another cool thing is the Cab block. You can mix up to four IRs each with independent Pan, Distance, Proximity, Smoothing (De-phase). And it has four channels so you can switch between four completely different mixes, instantly.

[3]Yes. This keeps the volume consistent regardless of the number of IRs and their mix levels. For example if you were to use two IRs and set each at -3 dB the volume would be half as loud. Behind the scenes it figures this out and compensates.

[4]Adjusting IR levels is not possible. Cab-Lab automatically normalizes IRs for "unity energy". 99.9% of the time this results in IRs that are the same volume but every now and then an IR will have energy outside the normal range of hearing which confuses the normalization routine. It's superior to the usual amplitude normalization but not without its faults.

The difference in having the cabinet before or after the effects is usually subtle. It depends on how non-linear or time-variant the effect is. For effects like EQ, which are linear and time-invariant, it doesn't matter at all. For slightly time-variant effects like chorus and flanger the difference isn't very pronounced. For highly time-variant effects, like pitch shifting, the difference can be marked.

[5]Linear means that the output is related to the input by a straight line: y = mx + b. Filters are example of linear systems. A cabinet IR is a filter. Distortion is an example of a nonlinear system.

[6]Since a cabinet is linear (or mostly linear) the order is unimportant as linear systems are commutative (a+b = b+a). However if the cab block is mono your effects will collapse to mono if placed before.

Now, if the system isn't linear (i.e. there's some distortion) then the sound will change. Also if the system is time-variant the sound will change but most modulation is wide-sense-stationary enough to not create a noticeable change if the order is reversed.

[10]Given that most post effects are linear or "wide sense stationary" the order of effects after the amp doesn't matter. Reverb -> Cab is theoretically equivalent to Cab -> Reverb because linear systems are commutative (i.e. a * b = b * a).

Pitch effects are not linear so putting them before the cab block will sound different than after. Anything that causes distortion is not linear so the order matters. If the distortion is subtle then the order is less important.

Javajunkie:

[11]You can place the effects loop anywhere in the chain (just add the fx loop block). Unless you are running a stereo cab or 2 mono cabs panned hard L/R, you may want to place stereo effects after the cab. The cab is a linear time invariant effect (unless you add drive) so effects like delay and reverb will sound the same before or after it. As Cliff and others have stated on numerous occasions LTI effects can be placed before and after each other and they will sound the same. Only when placed before or after non-LTI effects (drive, amps, et. al) it really matters. The one caveat there is that some effects are mono, placing effects before and after that makes a difference.

Bakerman:

[12]It depends on how you're panning. Assuming a mono signal sent to cabs: Stereo cab w/ Pan L and Pan R fully left & right will be the same output level as 2 mono cabs w/ balance L & R. If pans/balances are centered the 2 mono cabs will be 6 dB louder. Balance elsewhere would be between 0 and 6 dB louder, and balance doesn't correspond 1:1 to pan L/R for the same placement. Balances will need to be further toward -50 or 50.

The FM3 has the same Cab block functionality as the Axe-Fx III, but provides a single Cab block instead of two, supports two IRs instead of 4, and some functionality has been left out, including smoothing.

On the AX8, FM9 and FM3, cabinet modeling runs in an CPU accelerator instead of the core DSPs, which saves CPU. On the FM9, the second Cab block doesn't run in the CPU accelerator, so it'll take up more CPU than CAB 1. [13]

[17]An accelerator is a DSP unit dedicated to performing a defined task. In this case it performs convolution. The difference is that a "DSP" as we commonly call them is really just a microcomputer optimized for Digital Signal Processing. The term DSP most correctly refers to any device that does signal processing using numerical computations. That device can be an FPGA, ASIC or fixed hardware unit. In the AX8 it is a convolution processor.

Firmware 22+ for the Axe-Fx III (and corresponding FM3 and FM9 firmware) features DynaCab cabinet modeling. This allows us to freely position the microphone. Set the Cab block to DynaCab mode to be able to select a mic type and set its position and distance. Behind the scenes the appropriate IR is loaded. A graph visualizes the settings.

The built-in factory DynaCab IRs are 2048 samples on the Axe-Fx III, but the resolution can be lowered to Standard (1024 samples) to save CPU. On the FM9 and FM3 the factory DynaCabs are 1024 samples. Fractal Audio's commercial DynaCab Packs contain Ultra-Res IRs.

The Cab block offers parameters to let you select the speaker cabinet type, the type of microphone (condenser, dynamic, ribbon), the position (cap to cone) and the distance between mic and speaker. DynaCabs have no Proximity parameter.
