InstallAware

Hi All,
in my script before run the checkvc91_x64 , I show a wait dialog in non-modal mode, when the checkvc91_x64 is finished I hide the dialog.
If I run the installation in Windows 7 32bit all works.
If I run the installation in Windows 7 64bit in the checkvc91_x64 script the command "Find All Files $WINDIR$\WinSxS\mfc90.dll......" cause the display of many MessageBox with the error
%1 is not a valid Win32 application, ClassID:{56FDF344-FD6D-11D0-958A-006097C9A090} .

If I don't show the dialog all works also in 64 bit.

Thanks in advance for your support.
Steven

Could you let us know what version of InstallAware you're using (build is important)?

IA 9 Studio ( Build Moya.sp1.070409) .

Thanks,
Steven

Sorry I dropped the ball on this, but are you still having problems with this?
