Windows 7: clr20r30 error on windows 7

clr20r30 error on windows 7

I currently have installed a point of sale system on my system. I have tried multiple clean installs of windows 7 64 bit. Currently windows 2008 r2 64 bit server is installed. Everything will work on a xp32 install. The company that sells the point of sale will not respond. The problem shows up when I click on reports. They have included Reports for .NET Framework 2.0 (x86) and Crystal Reports Version 11 Runtime Module which appears to install correctly. I am running sql server2008.

This is the error:

Can you provide a link to the program?

Have you contacted their email and phone support? If you own a license, they should respond or risk sullying their reputation.

I have not yet purchased the program. I have downloaded their fully functional demo. I have tried contacting them about half a dozen times by email and phone. They say they will call back and never do. I will be purchasing this software if I can get it to work on a 64 bit platform. I am sure they are busy and don't want to ruin their name. Can I send you an email with the demo link?

Post it up here so we can look it over. But I will tell you that I would not buy a program with that level of support.

What is it exactly that you need such a program to do, as others will likely have better alternatives.

Unfortunately it is the only point of sale that works for my particular situation that we can afford. This is a link to the downloader .... . I have trialed it on my old xp computer and it works well other than a few bugs.
