Citrix Web Client 12.0 - “A remote application is trying to access files on your computer”…

We’ve had some fun with the new v12.0 XenApp Client – by default each user on web interface sites is asked when they launch applications that try to use the local drives.  The message below pops up, which is nicely redesigned since the previous versions.

If the user clicks Yes, access to resources such as local drive mappings is then enabled (read only if the checkbox was clicked).  Otherwise, you can get errors such as “The folder ‘c:\*.*’ isn’t accessible”.

If you want to avoid errors such as this, decide whether you want applications to have access to local drives (different for everyone I’m sure, but you probably do), create a text file called “webica.ini” at these locations automatically at logon:

Windows Vista and 7:  C:\Users\%USERNAME%\AppData\Roaming\ICAClient

Window XP and 2000: C:\Documents and Settings\%USERNAME%\Application Data\ICAClient

The file contents for allow access and never ask is:

[Access]
GlobalSecurityAccess=405
