This one is about an issue you may run into when Microsoft Word is virtualized and you try to open a DOC or DOCX file from a SharePoint site. Issue: When you have Microsoft Word virtualized and streamed to a client, if you open a SharePoint site, select a doc file and in the drop down list you choose "Edit in Microsoft Word" you may receive the following error.
Resolution: There are three possible workarounds for this issue:
1. Install the SharePoint Compatibility Pack from the Office CD on the client.
2. Save the document locally before editing.
3. Run Internet Explorer inside the virtual environment, either by opening it directly from a virtual app or by adding an OSD for it to the package.
