Restoring Archives to Mailboxes

Greetings,

my company needs to restore several Quest archives into the originating mailboxes while keeping the folder structure, or exporting them into a .pst.

Through searches within this forum i found the recovery manager for exchange which will suit our needs.

Installation was successful with some issues which we solved.

Unfortunately the program wont start with the error "either there is no default mail client or the current mail client cannot fulfill the messaging request etc."

Outlook is installed an also the default program for Email.

My question: Is there a step-by-step-guide on how to correctly install the recovery manager, especially where? Maybe i made a mistake here.

We are still using Quest Archive Manager 4.8, is this a "showstopper"?

I wanted to open a supportticket, which is not possible at the moment due to unknown error.
