Cannot cleanup (uninstall) already installed (by opera and myself) unite apps and widgets, and..

..cannot install new ones either. Both type of files are downloaded into C:\Documents and Settings\<ACCOUNT>\<LOCAL_SETTINGS_LOCALIZED_NAME>\Applications Data\Opera\Opera\temporary_downloads, but:

1. In case of Unite they *seem* to be installed but whenever accessing an app's URL I get a message saying that address does not exist.

2. In case of widgets when trying to uninstall one I get the message (translated from Swedish): 'Didn't succeed to find the script file "C:\Document and Settings\<ACCOUNT>\<LOCAL_SETTINGS_LOCALIZED_NAME>\Application Data\<APPLICATION>\uninstall.vbs".'.

In case of *installing* widgets the message is: 'The location "C:\Documents and Settings\<ACCOUNT>\<LOCAL_SETTINGS_LOCALIZED_NAME>\Application Data\Opera\Opera\temporary_downloads\<WIDGET>.wgt" is unavailable or does not point to a valid widget'.

The problem clearly relates to the fact that Opera resolves the localized path to the Local Settings folder incorrectly after the initial download step of the widget install. I say this because my systems localized name for the Local Settings folder is resolved to "lokala inst{trash}llningar", where "{trash}" are two wrong characters replacing an otherwise correct "a" with two dots on top. But as mentioned downloading the file in the initial install step into the temporary_downloads folder works fine !

Note: I'm on (semi)swedish Windows XP SP2, Opera 10.53 (tried 10.54 previously).

Bumping, and also notifying I simply cannot install anything else either. Just tried installing voice controlled browsing for the first time. The files are downloaded into the aforementioned troublesome folder, but they are not applied, bloody hell !

-edit-

I have monitored Opera with Process Monitor, and it does fail alot (but far from always) on QueryOpen operations, haven't noticed any suspect pattern in the full file path though, so I'm not sure what is the problem.

-edit 2-

Found out Voice is not supported anymore ?

But, the problems with some unite apps and all widgets remain unsurprisingly however..

Seems Unite app (un)installation works fine, which may be have to do with an(other) Opera reinstall I did after previous posts.
Widget (un)installation continues being completely broken however.

I have exactly the same problem with Widgets. Unable to uninstall with the same error message. Sometimes difficulties with installing and setting up widgets. I'm rather unhappy with the recent changes in widgets.

Opera 10.53, Win XP.
