Server power fail, now MP1.3 won't install (1 Viewer)

[ArnoldGoat]

I had MP1.2.3 server running, and began updating to 1.3. Then the power failed! It doesn't seem to have damaged V1.2.3 which started OK when the machine started up, but it must have left something behind that stops the deploy tool running.

I get to the prompt 'start with the installation now', but when I click OK, I get an alert headed "MediaPortal Installation Tool" with the message "Unhandled exception ... object reference not set to an instance of an object", then the stuff at the end of this post.

I would like to try to avoid doing a fresh install for the usual reasons. Is there anything I can do to give the installer what it wants?

Thanks.

Understand the desire not to do a full, fresh install but from recent experience, power fails can cause so really odd problems and if it's broken during install, fixing it may by far more of a problem than it's worth and full clean up and reinstall may be your safe bet.

However, no reason you should loose all, there are a number of backup options to consider, in terms of getting service back running, these can save you many hours - plugins sadly, unless you download them as files and then install as local via MePo Extention Installer (I do, makes building replica easy), those you have to reload.

See https://forum.team-mediaportal.com/...of-the-important-settings.117449/#post-975862 which may help.

Thanks for the advice JCMP.

I only have 2 or 3 server plug-ins, so I am thinking that the Export/Import thing in the config utility will do. (It's a server-only machine.) It seems to save the schedule, which is the trickiest thing to reproduce. MP doesn't seem to have a registry entry, so I am assuming it looks for the folder name to see if there is an existing installation? I've dumped the tables from MySQL in case it comes to rescuing data from them.

 

[JimCatMP]

I think your correct, it's checks to see if files exist rather than rely on registry (wish more software did that), so a full clean out will purge all files from system and really is clean - this includes the directories - so make sure you do NOT store the backups or export in MePo directories - done that, dutifully made backup copies only to find MePo is 100% in earnest when it cleans itself.

Dumping tables so you can re-import is a sound move, the import should ensure your DB is error free just in case it also got a little bit of a byte bashing due to power loss at critical moment.

Good luck with re-install, power company permitting, hopefully it'll be quick and clean this time around.

Well, I moved the Team MediaPortal folders from Program Files (x86) and Program Data to a different disk, but the Deploy Tool still doesn't want to play - same error. Is there anywhere else I should look? I've searched for "*mediaportal" on the C-Drive, but nothing's there. The power loss was unfortunate, and my own doing. I have a UPS to guard against this sort of thing, but the plug in the back of the PC wasn't pushed in firmly enough!

 

[ArnoldGoat]

I trawled around in the deploy tool code and found that in fact it does look in the registry for the uninstall key, which had been deleted. The solution was to persuade V1.2.3 to reinstall, and proceed with the upgrade to 1.3 which (so far) looks good. Thanks for your suggestions.

 

[JimCatMP]

Your welcome and we all hope your upgrade is clean & smooth.
