Installation Issues
I had Inventor 2008 on my desk top computer for about a year. Ran fine though I used it very little. One day I ran a Registery Cleaner program and Inventor stopped working after that. I tried to Uninstall Inventor and could not. Had too take it an IT guy to get that accomplished. Reinstalled Inventor 2010 with great difficulty. It did finally install though it stopped three times telling me I did not have permission to upodate registery files. I adjusted permissions and like I said it eventually installoed but it will not launch. I uninstalled (without problem) and tried to reinstall several times but with the same results. So I decided to reinstall 2008. Attached are the errors.
I don't know what to do now.
