Do a search for each of these files using the Start/Search feature, one file at a time.
Stdole32.tlb
Stdole2.tlb
Stdole.tlb
If any are missing or not showing as in %SystemRoot%\System32
Put your XP cd in your CD drive.
If it aouto runs cancel the window that appears.
Go to start/Run and type in the box cmd.exe and click ok.
A Dos window will appear.
This assumes that your CD drive is D, if it is a different letter change the d in CD /d C:\ to the correct letter.
Type : CD /d C:\ then hit the enter button.
This will then change to a new line starting with C:\
Depending which file is missing then type either
Expand <CD-ROM Drive:>\I386\stdole32.tl_ %SystemRoot%\System32
Or
Expand <CD-ROM Drive:>\I386\stdole2.tl_ %SystemRoot%\System32
Or
Expand <CD-ROM Drive:>\I386\stdole.tl_ %SystemRoot%\System32
After typing that line hit enter again.
You must type it exactly as written with all the spaces and punctuation marks, upper and lower case dont matter though.
Unfortunately you cant copy and paste in dos so just type carefully.
If you need to add 2 or all 3 files then repeat the process for each extra file
