I think you did the right thing by trying to ugrade from Reader 5.0 to Reader 9 but was a bit unlucky as you faced this issue.Now try doing following:
•Download the Windows Installer Cleanup Utility from http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html and run it;
•Run the tool from Start | Programs | Windows Install Clean Up;
•Select 'Adobe Reader' and click the "Remove' button; close the tool;
•Download the 9.3.4 http://ardownload.adobe.com/pub/adobe/reader/win/9.x/9.3.4/enu/AdbeRdr934_en_US.exe and run it.
how about using "system restore" to an earlier date?
Thaks for your help........But I'm afraid to delete my Adobe 5. first.... What if I can't install the Adobe 9 ? Then what would I do?
But I'm afraid to delete my Adobe 5. first.
Why want you delete Acrobat Reader 5 ?
