Adobe Reader does not show printer and Windows 7 is unable to change default printer

Client called today to report of problems related to printing.


She's generally able to print to her new Ricoh MFP C5000 Copier machine, but was unable to see this printer driver in Adobe Reader X. Strange as it may seem, this happened because I've set the printer up on a different domain user profile.

I repaired Adobe reader, ran all the updates, but to no avail. Even tried changing printer name to something shorter... Nope, it doesn't work. Gave user the change permission on the printer properties...nope!

Finally, as I was trying to set the printer as a default, I encountered an error:  

Unable to setup Default Printer, error message: 0x00000709

As I was looking through the net for similar issues, I encountered this forum post here.


I had to read through the entire 4-page long document and I finally figured that I could simply change the permission on the registry to allow EVERYONE full access to this registry key:

Found out that I didn't have the right permission to access the registry key here:

 HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows

All I needed was to give myself the full access permission and everything was fine after the reboot.

The thing I couldn't figure was, why is it only Adobe Reader X having this issue with not being able to detect the printer. Hmm...
