Adobe Reader 8.1.2 unable to print on Sharp 450 model

Question

Hello
After an Adobe upgrade, PDF's cant print to Sharp 450 models. Simply says "the document can't be printed" However, if we check "Print as Image" it's prints with no errors. This issue is printer specific because pdf's are able to print ok to other Sharp printers on the network. Clients are running Win XP Professional. We have uninstalled and reinstall Adobe and we have the updated 450 driver from Sharp. Has anyone seen this specific issue, or at lease with other printers. Thanks for your help.

Thanks for the link but my problem is with EXE files (amongst others) so, as stated in the MS article, you can't use that method to change the behaviour.
By comparing to another machine, I have found is a set of keys in the HKCU registry that shouldn't be there -
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe]
"Application"="AcroRD32.exe"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWi thList]
"a"="AcroRd32.exe"
"MRUList"="a"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWi thProgids]
"exefile"=hex(0):
Having now removed them using REGEDIT (& I remembered to back up my registry first!) I have now re-installed Acrobat Reader without experiencing problems (haven't rebooted yet, but I'm pretty sure it's fixed) - e.g. I can still use REGEDIT, launch IE7 or Firefox from icons that didn't work before.
I have no idea how those keys got there, but they're gone now ;-}
