SKETCHUP PRO 7 -- problem with installing!

hi folks, i'm having some trouble installing the trial version of sketchup 7 pro!!!

after it unpacks the installation file, i get the following error:



Setup has detected that the file
'C:\DOCUME~1\Amer\LOCALS~1\TEMP\VSD1A.tmp\Conversa ntDotNexFxIntel\dotnetfx.exe' has changed since it was initially published. Click OK or retry the download. or Cancel to exit setup.



WHAT DO I DO?!?

any help appreciated! thanks ....

What happens when you click OK or retry the download?

You might want to use CCleaner and clear out your temp files.

CCleaner - Home

Also try Windows Update and take all critical (express) updates.

Sketch up Pro 7 requires .NET Framework 2.0 or later.
