I'm getting the same error on launch myself. It's Win7 x86 and not x64. Dispite the error it appears to function normally.
I've noticed that it's only affecting a single user's profile, others appear not to have the same problem. The user's profile used redirected folders for his desktop/documents/favs/etc. And referenced them using a mapped drive which was causing an error upon installation. I removed all references to the mapped letter replacing them with a UNC reference instead. But still plagued with the 0xc0000710 error.
If anyone can offer some suggestions...
Looks like the problem is related to the Protected Mode feature found under Edit.Preferences.General.
Adobe Reader X (10.0.1) on HP p6230y desktop running Windows 7- 64-bit
I get the same error:
AcroRd32.exe - Application Error
The exception unknown software exception (0xc0000710)
occurred in the application at location 0x77e9a341
Click on OK to terminate the program
I get the error whenever I open any PDF file for the 1st time from any source, such as,
e-mail attachment, HTML editor, and online link, including this PDF test page:
Uninstalling and reinstalling Adobe Reader X several times has not removed the error.
You asked if I'm using a folder that's being redirected. No, not to my
knowledge anyway. When this issue occurs it is usually when I am opening a
.pdf attachment I received in an email, but not exclusively. It also
happens when I open a .pdf from my desktop. Important to note: it doesn't
happen all the time, but it's probably at least 50% of the time.
Thank you for your assistance!
