HI Dov,
I'm not sure why you remain so incredulous.
This worked for LaurieAnn, twice.
Then, I was able to fix 4 PC's before I left work tonight.
Regardless, I will elaborate to try to help....
Prior to Christmas, we had no problems with the PDF printer on any of our PC's.
I first became aware of a problem in mid December when we replaced 2 PC's with WIN7 PC's.
The 2 new PC's came preloaded with WIN7.
After installing Acrobat XI Pro and upgrading to 11.0.10 I found that the 2 new PC's could not print to PDF.
When I looked into it further I found that none of my engineers with WIN7 and XI (11.0.10) could print to PDF.
Regrettably, I can't confirm when the problem began.
I was personally running XP with a older version of Acrobat Pro prior to mid-Dec (with no problems).
My Engineers hadn't complained because they found a work around (convert to PDF).
For me, the work around is not acceptable (caused hours of frustration and lost productivity).
I tried and failed on 2 occasions in December to find an online solution.
Today I found this thread and persevered, with no success, til I found LaurieAnn's solution.
When I tried LA's solution on my PC (including deleting the existing PDF printer) it worked immediately.
I didn't even have to reboot :-)
On the next PC I forgot to delete the PDF printer first and the patch did not work.
I deleted the PDF printer and reloaded the patch with instant success.
Then I followed up on 2 more PC's with instant success.
The miracle patch file name is: AcrobatUpd11010.msp
Trusting this helps you Dov.
It definitely helped me :-)
