I've been working on a problem with one of my clients upgrading to Peachtree 2010 Premium - Accounting Edition. I have done previous installs with KAV (specifically, KAVWKS 6.0.387, without NDIS filter) for 2009 with no problem, so I dismissed the issues early on as a result.

Symptoms are basically that when it begins to launch the actual installation and you agree to the terms, it crashes with this output:

Faulting application idriver.exe, version 10.50.0.125, faulting module msvcr90.dll, version 9.0.21022.8, fault address 0x0006c955.

I reinstalled InstallShield, tried as other accounts, reinstalled VisualC Runtime 9.0 redistributable, nothing. After a while I had to be sure so I removed KAV and rebooted. Install now completes without issue. I have reproduced this on 3 machines.

I am unsure if this will require a module update or just a definition update to address, but a number of companies that I do support for will be calling to get this done - having to remove KAV and reinstall just to do it is kind of a pain.

Just wanted to bring it to your attention and if you need any information to diagnose further please let me know. This is running Windows XP SP3, all latest patches.

Hello,

Try to enable "Compatibility mode" under "Settings" > "Service".
Reboot the computer in order changes to take effect, and see if the error still occurs.

That was already done by our WKS policy.

Looks to me this has something to do with Peachtree 2010, here is somebody
with the problem different program... same error... in the end the problem was fixed by the supplier of the program....
