While opening certain PDF files we have the problem that the user is presented with a message that he does not have the rights permissions. This happens twice, after that the users gets an empty page with the message the Adobe version might not be up to date. We use Acrobat Pro 10, but this also happens while using Reader 11.0.8. On our windows 2008 terminal services machine this could be fixed by giving the user rights on c:\ to create and remove a file. :O. On windows 7 this doesn't work probably because of UAC. But we've tried every solution to that available on the internet, disabling uac, changing uac options, changing rights on userprofile folders, changing rights on c:\ but to no avail. When using process explorer we can see it wants to create a temp file p328hkl.tmp or something like that on C but it can't and immediattely after is shows the error on screen.
Anyone who also has this problem or solved it? There are no problems with simple self made pdf files/scans but only with certain types of pdf files for which it tries to create a tmp file.
Thanks,
Peter
