2. Edit GoogleSketchUp7.msi with Orca, delete "VersionNT>=501" in LaunchCondition
3. Run GoogleSketchUp7.msi. During installation there was a warning "Could not write value SketchUpModule to a key". I just ignored it
When running SketchUp the first time, I encountered "Create File failed for C:\windows\Temp\skpB154.TMP" too. Also the toolbars are corrupted. However these problems did not affect the functioning of the program
slhk are you using MSInstaller version2 with this MSI file?
