Error 1304

Hi

I'm trying to install Acrobat 8.1 Pro onto Vista Home premium 64 bit.

I get an error message "Error 1304 - error writing to file ..........."

Adobe give some guidance (in
http://kb.adobe.com/selfservice/view...ernalId=329117) on how to
get around this for Win XP, but not for Vista.

One of the suggested methods is as follows:-

"Solution 3: Use the CACLS command to assign full administrator access to
the All Users folder. (Windows XP Professional and Home Edition, and 2000)
Use the CACLS command in a DOS window to manually assign full Administrator
access to the Documents and Settings\All Users folder. Full administrator
access allows the installer to create the files that Acrobat will need.
To use the CACLS command to manually assign access:
1. Log in as an administrator. If you don't have administrator rights,
contact your system administrator for assistance.
2. Choose Start > Run, and then type cmd in the Open box. Click OK.
3. Type the following commands; include quotation marks and press Return at
the end of each line (also make sure to enter spaces between /T, /E, /C and
/G in the third line):
c:
cacls "c:\Documents and Settings\All Users" /T /E /C /G administrators:F
exit"

Can this be used with Vista, presumably pointing at C:\Users ? Would the
switches be the same?

Thanks
