I had to reinstall my Prepar3d academic license on the same computer because a problem with my OS (W7x64) I I reinstalled all the software because something was wrong with it (I mean, the OS).

I reinstalled everything on the same computer and I assume that you would have some kind of hardware fingerprint or IP detection related to my license to avoid install it in a second pc and allow me a reinstallation without problems.

This is the same pc where I made the first P3D install, but the license is no longer active for this pc.

Is it possible to reactivate this license, don't know how to demonstrate you that this is the true original computer with a fresh OS.

Many thanks

Mario Valotta

license details: sent by email and through the store

We have some details on this on many other stickies and posts of the forums.

Simply email with your reactivation request and your license id number and details and they'll fix you up.

I wonder, is this the same as MS with FSX, i.e you get a seemingly random number of reinstalls no problem, then have to contact the vendor i.e MS in the case of FSX to re-invigorate the serial no. Or will this be req'd by LM P3D with every reinstall.

With MS it seemed entirely random, some folks reinstalled regularly when it first cam out and never had the issue, others did the deed once or twice and had to endure call centers. I was led to believe that MS flushed out the Db periodically, but I never did get to the truth of that.

Recently I had a fab time trying to activate FSX and failing. I called and was informed that "we no longer support that product" Then magically 20 mins later the on line reactivate worked strangely enough. Oh I drone on...

Basically I am asking after all that, what is LM P3D's policy on re-activations?

I just went through this and LM was very prompt and professional. The cause was all my own stupidity. I very much appreciate their promptness in reactivating.
