Virtual Applications FAQ

Yes, you can access the Virtual Applications from anywhere with an Internet connection.

Please see our Working with VApps Files section. 

Open the application of the file you want to open. Go to the File menu, and click Open. By default you will see the Virtual Apps Documents folder in the Open window similar to the Save As window previously shown. If you have saved any files in this folder before, you will see those files. Select your file and click Open.

It is highly recommended that you save any files on the :V drive. To open these files, click Open from the file menu, and from the drop-down menu of the Open window, select the :V drive. If your previously saved files are stored locally, transfer the files to the :V drive  (Refer to Transferring Files) to open them from said drive. We do not recommend opening files directly from the local computer.

If the file is not saved and the timeout occurs, the file will be lost, the application is kept alive for 30 minutes. If the file was saved on V: drive within VApps, the file is permanent.

You have 500MB disk space available for your Virtual Apps Documents folder.

There are many possible causes, the most common one is that the plugin has not been installed. Another reason for this error could be that the browser is not aware about the ICA extension. On the Internet Explorer menu, go to Tools > Internet Options > Advanced tab. Under Security section, unselect the Do not save encrypted pages to disk option.

Restrictions message

This message can be safely ignored. It normally happens when doing a File > Open or File > Save operation. It is an application based message which shows up when the application finds certain files it needs to access restricted on your local drive. Afterwards, it self corrects and ignores the check.

Yes, Virtual Applications is not available between 2:30 a.m. and 3 a.m. daily for system maintenance. Please save your work before 2:30 a.m. to ensure your work is not lost.
