some applications cannot access shared folders in windows 7 guest

[matteo sisti sette]

I installed Guest Additions on the Windows Guest, created a shared folder, connected it as a network drive in Windows Guest.

The shared folder works, I can read and write to it from the guest, and browse it with Windows Explorer, however:

• most applications show it with a red "X" on it as if it was not accessible
• many application will be able to open, browse, read from and write to it despite showing the red X
• SOME applications will instead refuse to open the network drive and give an "access denied" error. For example you can't open an HTML file residing on the network drive with Internet Explorer
• .air packages (installation packages for adobe AIR) won't install if run from the shared folder (you have to copy them to the virtual disk, then they will work). The air will run from the network drive, but when it is supposed to ask for confirmation to switch to admin privileges, istead of popping the dialog, it will output an error message and abort installation

The last issue is indeed a special case of the previous one: AIR installer cannot handle properly the .air file residing on the network drive.

There seems to be a privilege issue with shared folders.

Looks related to bug #5732, possibly a duplicate.

1. Only execute fails, right ? (you can copy files normally)

2. If you use "Administrator" account the problem is gone in my case. Please try it.

It is probably related, but this is definitely not the same issue described there. Indeed this probably INCLUDES that issue as a special case.

Not only executing fails, much more. As I mention, also OPENING files, or BROWSING folders from some applications fails.

For example open Internet Explorer and chose File/Open and browse for some html file in the shared folder, it will not open (it will show the same error page as if you try to access the internet without connection). Some other applications, when browsing for opening or saving a file, won't even let me open the shared folder (network drive) for browsing.

However, Windows Explorer (i.e. browsing folders from "My Computer") does work without problems, So yes, I can COPY a file, including an exe file from (or to for what matters) the shared folder.

It seems to me that some permissions are denied when trying to access the shared folder. However some of the cases where the access fails shouldn't need admin privileges at all: for example you shouldn't need to be admin to open a html file located on a network drive.

By the way I now realise my original post is hardly readable, I'm sorry. I wrote it properly, but this form eliminates single linebreaks without warning the user of it.
