Try this out.

1. The issue is resolved in Service Pack 2 for Crystal Reports for Visual Studio 2010
2. Service Pack 2 and associated MSM, MSI and ClickOnce files can be found on the Crystal Reports for Visual Studio 2010 Reference page
 

3. Alternatively, rename the C:\Temp to something else - such as C:\Temp1 so the embedded designer can't find the dire

What version of Crystal?

Is the Win7 machine 32 or 4-bit?

try going into safe mode from there you can make windows 7 act like xp on the security tab of the c: drive you need to do it in safe mode

but also you could try xp mode which is a virtual xp running ontop of windows as thats m$ way of getting all applications working in windows 7

err

Alternatively, rename the C:\Temp to something else - such as C:\Temp1 so the embedded designer can't find the dir

just try that without doing my security fix above you cannot as even in admin you have no admin rights to c: thats been changed in windows 7 from previous so doing my security fix means local admin in windows 7 is like previuos versions
