Greetings,
When I did my taxes last year (March 2012), I downloaded some pdf files from the IRS. Form 1040 was a writable file and I filled it out as needed. This file was saved on a Vista machine running XP. A few months ago, I upgraded that pc to be Windows 7 SP1.
Today I'm getting ready to do my taxes for this year. When I double click on last year's Form1040.pdf, I get the following error message:
There was an error opening this document. Access denied.
Interestingly, I can open other pdf files, like the Form 1040 Instructions. I do not think that I password protected my Form1040.pdf. The reason that I think it isn't password protected is because I'm not being prompted to enter a password.
I copied the file to an old spare XP machine (XP Home, version 2002, SP3) that I have and it opened fine. It did not prompt for a password. I printed copies of last year's forms from that XP machine, so this isn't an emergency for me, but it is mildly annoying that I can't figure out what's wrong.
I have Adobe Reader XI version 11.0.2 installed on both machines (the Windows 7 machine and the old XP machine).
To summarize, it was created on Vista, I can't open it with Windows 7, but I can open it with XP.
Normally I would consider uploading the file in question, but in this case, I hope you'll agree that might be a bad idea!
Advice on how to get this to work on Windows 7 would be appreciated.
