Vista 32 sp2 with clean working instal of 1.2.0alpha.
Both 1 and 3 upgraded fine Tvclient and MP gui. no errors reported during.
I did have an error with mpcSubs.dll not being found (not registered ?) causing severe problems with any video playback avi and ts. (eventualy found that disabling subs in mp/video/subs cured this) but I did the following first.
So I did a full uninstall and fresh instal of both 1 and 3 Tvclient and MP gui. no errors reported during. (still mpcSubs.dll problem as above).
I must say the installer is the best i have used. Didn't force a stop when no internet detected and correctly detected all required installs, very smooth and trouble free both upgrade and clean/fresh install.
Can't post logs, sorry, have no interenet connection at home and need to walk two miles to the nearest library to use , max 1hr a day, a pc with very limited use.
Thanks for the report
Will try to see about mpcSubs.dll, like it was related to same part of source maybe we need to compil it with latest change.
I will repost build to test to confirm that all is ok
Seb.
