From: Claire on 28 Jun 2010 18:39 Thank you Karl. Now I understand, I hope. When installing app to be used by all users how should the program be installed? I understand that HKLM must be used regarding the registry but how about app path? My app creates logs, keeps preferences in ini file, adds menu extension to IE browser and installs plug-ins for FireFox. How to do that for all the users? Any pointers appreciated, Claire "Karl E.

Have you tried checking the Privilege Level option for the application shortcut (Compatibility tab) to "Run this program as an administrator"? If this fixes the problem then you probably need to tweak the security settings on the APPDATA folder. Viken

CSIDL_PROGRAM_FILES - But really, your install app should be wired for that. The HKLM analogy is important, though! Don't brush it off so quickly. The concepts surrounding accessibility to that are the same as for the folder you posted about. > My app creates logs, keeps preferences in ini file, adds menu extension to IE > browser and installs plug-ins for FireFox. > How to do that for all the users? You need to choose whether you plan to follow the rules or not. Advice can only be based on that. The general rule, though, is that you can't share like that anymore. If your application finds that "this" is the first time it's run, then it grabs a copy of that generic data and molds it to the current user, forever disassociating itself at that point. So, to specifically answer your question, in the vaguest possible terms, I'd say, "One at a time" and/or during installation. -- ..NET: It's About Trust! http://vfred.mvps.org

For example, an application may store a spell check dictionary, a database of clip-art or a log file in the CSIDL_COMMON_APPDATA folder. This information will not roam and is available to anyone using the computer. By default, this location is read-only for normal (non-admin, non-power) Users. If an application requires normal Users to have write access to an application specific subdirectory of CSIDL_COMMON_APPDATA, then the application must explicitly modify the security on that sub-directory during application setup. The modified security must be documented in the Vendor Questionnaire. http://msdn.microsoft.com/en-us/library/ms995853.aspx#w2kcli_req42 -- ..NET: It's About Trust! http://vfred.mvps.org
