Hi Melissa,
If you right click on 'My computer' and choose 'Properties, what is the build number showing for Windows XP?
I'm assuming you're trying to install when you say 'open'?
Let us know if these steps help:
===========
1. Backup your PC/files for safety.
2. Use Start=>Programs=>Accessories=>Disk Cleanup
clear your Internet files and temp files.
3. Restart the PC. You may want to set a restore point.
4. Locate your 2007 Office Professional Beta 2
download file and note the folder/path location.
5. Create a new folder on your PC and note that
folder/path location.
6. Use Start=>Run , and on a single line, type in
the following (using the path & file names from
Step 4 & Step 5, above)
"drive:\Step2PathOfDownload\downloadfilename.exe" /extract:"Step3path"
example: If saved your download in a '\downloads' folder and then created a new empty folder named Off2007ProB2CD1 to hold the
Office 2007 CD image that you're about to create, then the Start=>Run line would look like this sample
"c:\downloads\OPPLUS-EN.EXE" /extract:"C:\Off2007ProB2CD1"
7. If the extraction is successful (you'll get a dialog box telling you it was after a few minutes). Shut down all running apps,
utilities, email, messengers, and antivirus.
Now double click Setup in your new Office 2007 CD image folder.
Or, if the extraction in step 6 does not succeed then
the Office 2007 download may be damaged/corrupted. To help determine that usse Start=>Run and type
%temp% {enter key}
then locate in that folder the the Setup.exe(xxxxxxx).log
(file) just created (check the date and time if there are several) and see if that log file yields has any clues on where the
extraction failed.
Post back with the results either way please.
=========
I have downloaded the new office 2007, but when I try to open it, it displays
must have windows XP of later. I have windows xp, and have updated it.
Please advice why it wont work,>>
