During the   update,   I had a problem .   I could not   run the   application,   so   started to   restore   the previous version.

I downloaded   the installer from  the  http://archives.manageengine.com/service-desk/

Unfortunately,   I get the error ! !   Such as   set out in the annex.

Now I can't   go back   to the previous version   and the system   does not work.

I tried to install   version of the   9030   32   and 64 bit   shows up   the same error.

The same   error   I got   when I tried to   install   version   8029 .

On the destination disk   I have   free   195   GB,   on the   20 GB   system , I   restarted   the system ,   antivirus   turned off   and nothing helped.
