I virtualized the installation of Adobe Acrobat Pro XI v11.0.11 together with Microsoft Office Professional Plus 2010 v14.0.7015.1000 x86, carried out on Windows 7 Enterprise v6.1.7601 x64, making use of VMware ThinApp v5.1, I also created an entry point for Windows Explorer (%SystemRoot%\explorer.exe), which allows me to 1.Open .pdf, .doc, .docx, .xls, .xlsx, .ppt, .pptx and all other file formats supported by Adobe Acrobat XI and Microsoft Office 2010 with double clicks without the need to create file associations first 2.Get working right click menu commands such as "Convert to Adobe PDF" and "Combine files in Acrobat..." 3.Get thumbnails and file previews in the Preview Pane together with their properties in the Details Pane in the virtualized Windows Explorer Now, the problems which I am facing are that I am getting file previews in the preview pane inside VIRTUALIZED WINDOWS EXPLORER, for Microsoft Office file formats but not for .pdf files, even the thumbnails are not generating for every .pdf file
