You've posted two more errors.
1. The IRT runs just fine with any normal installation. Yours was corrupt.
2. It is never wise or recommended to transfer Outlook data by exporting it.

Wrong. If you installed Office, you installed scanpst.exe.

It appears that sometimes somehow scanpst.exe is not installed with
the office installation.
You can find more information about how and where to find scanpst.exe
herehttp://scanpst.org/scanpst-exe-location-where-to-find-scanpst-exe
Yes you are right, you can find the scanpst.exe but you cannot run
it...
the error goes like that
This application has failed to start because SCNPST32.dll was not
found.
Anyway, even if you can find the file, the I do not recommend using
it.
This is because it is better to create a new fresh PST file by
exporting all the mailbox data out of it.
You can for example use the Scanpst Pro at
