Hi,

Sorry, I don't know if the translation is correct.

Monopoly sucks.

I only have two small clients that use QM. They want to leave the MV.

Me trying to revive the systems, I can't get a simple information about license renewal.

Martin always served me very well, quickly. The best support I've ever had. Congratulations.

The company that maintains the monopoly of MV technology is a disaster in relation to small companies.

This monopoly tends to end our legacy, as well as scare away new users.

Att.,

Cleber.

That's why ScarletDME is important.

Can you clone the hard-drive, install the (32-bit) version, and see how
it goes?

Cheers,
Wol

I'll wait, but if I don't get an answer from the monopoly that now dominates the MV. I'll go for other options.

It won't work. They jimmied the opcode numbers on purpose to prevent code
compiled in the commercial build of OpenQM from running on the GPLed
version.

A backup/restore of specific accounts could work ok, providing the source
code for any custom software is available to be recompiled.

Do we know what the changes were - what the QM opcodes are compared to
the ScarletDME codes?

Or some mug could write a re-compiler :-)

I think I'm suddenly about to get my new laptop finally set up and
working "just right", so hopefully I'll be devoting a bit more time to
the project ...

I don't, no. It was obscured on purpose.

A decompiler would certainly be handy. :)

  • They jimmied the opcode numbers on purpose to prevent code  compiled in the commercial build of OpenQM from running on the GPLed version.

 

This is not true though there have been massive changes to the object code format since the GPL version was released.

 

Beware of the legal pitfalls of reverse engineering the commercial product. This is explicitly banned in the licence terms.

I recall seeing a comment in the code that specifically mentions that the
opcode values used in the GPL version are different than the commercial
version in order to prevent binaries from one running on the other.

That might be moot in the face of Title 17, Code 1201, Paragraph f,
sub-paragraph 1. However, I'm not a lawyer, and this isn't legal advice.

Well that looks like US law to me, so it doesn't apply over here ... :-)

And I think bans on reverse engineering tread a VERY fine line on the
border of illegality in Europe. I'd have to investigate.

I am aware that it's dodgy territory, though ...

Surely a re-compiler is only useful if the customer has lost their source code? You cannot decompile the system level stuff that comes with the product, even though a lot of QM is written in BASIC as I understand it.

If the customer has their source code, then they could just try compiling it on Scarlet. When I checked out the source code for scarlet though, it would be seem to be impractical to go backwards from the commercial product to the Open Source version. 

If the customer is using a commercial package, then they could ask the vendor to move to a different platform.

Well the OP mentioned "licensing" and "reviving" the systems.
To me this sounds like *some* thing has caused the systems to be unstartable, meaning you can't log in at all

Maybe a message like "your license is out of date, you must upgrade your license...."
It doesn't really sound like the situation where you can even get inside your system, to do anything, before you fix this first.

But how can get to the object code without needing a license, but not the source code?

I think this thread has gone off the rails.
The OP did not mention trying to get to the object code, or the source code.
He only mentions trying to revive a system, and trying to get it relicensed.

You would not need to relicense something unless it complained that it was unlicensed and then died immediately.

The thread went where it went mate - there are no internet rules saying people can’t follow a path. Not sure why you thought this would be a useful addition to the thread.
