Cab1.cab

[Dunstan Jomphe]

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.

Unable to install Alteryx Designer 2023.1.1.23, getting error as "Source file not found: C:\...\cab1.cab. Please verify that the file exists and that you can access it". The prompt has two options "Retry" and "Cancel".

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.
