If your current version is working fine we generally don't recommend reinstalling it. If you have version 8.4 installed that came with HM2 then you might see some improvements updating to version 9.3.x which is the last version HM2 supports.
Make sure windows is fully updated until 'No New Important Updates are Found' (this may require multiple restarts and multiple 'check for updates'), including Internet Explorer (even if you use a different web browser).
Please note that reinstalling PostgreSQL will mean losing all your old data. If you have access to HM2 and your database was not corrupt then please follow these instructions for backing up your database as a precaution in case you cannot reconnect after reinstalling PostgreSQL.
If you cannot access the database in HM2 then you can backup your database using this method but if your database was corrupt then the best solution is to reimport all your hands from C:/HM2archive folder or if your pokersite supports it you can request all your hands and summaries and reimport them as restoring a corrupt database will just restore all the problems you had.
1) Uninstall PostgreSQL from the Windows Control Panel.
2) Delete the \PostgreSQL\X.x\data folder that is left behind.
3) Delete the sub-folder(s) in c:\users\username\appdata\roaming\HoldemManager\Da tabase (XP - c:\documents and settings\username\application data\HoldemManager\Database).
4) run the command - start > programs > accessories > command prompt > right-click > run as administrator
Code:
net user postgres /delete
After you click 'Enter' for the code above also do that same for this code:
Code:
sc delete postgresql-8.4
and click 'Enter' again.
5) Restart your PC
6) Install PostgreSQL 9.3 from here.
7) Once installed you should disable the postgresql logging as instructed here.
If there is still an issue, we need to know the error - it is in the %Temp% folder - bitrockinstaller.txt file. *If you can't see it, turn off the windows option that is hiding that directory. http://faq.holdemmanager.com/questio...es+in+Windows+
