QUESTION:
What can cause the appearance of an error message when updating ProTool (Pro/Lite) V5.2 from SP2 to SP3?

ANSWER:
At a level of about 35% completion of updating your setup aborts with the message "Cannot process Ptreg.dat".

Cause:
There are multiple different versions of the "PTREG.DLL" file on your computer.

Remedy:
Via "Start > Find > Files or Folders…" find all the files with the name "PTREG.DLL" on your local hard disks. Delete all them except the one in the ProTool directory.

Note:
The correct file must have the following properties:
"Version 5.3.0.23 of 04.08.2000 02:11"
You can have these file properties displayed by right-clicking the "PTREG.DLL" file in the ProTool directory and selecting "Properties".
