RSFX Driver Removal

steps to correct this issue: We need to obtain the product GUID from WMI using WMIC so that we can use the MSIEXEC /X {GUID} command to remove the software. Open a command prompt as administrator and type: WMIC PRODUCT LIST to get a list of products and the GUID associated with them. I found using the following command works best: WMIC PRODUCT GET Caption, IdentifyingNumber > c:\info.txt Once you have the GUID of the software you want to uninstall you simply type: MSIEXEC /X {GUID} Software is now uninstalled and you can proceed. *note* the steps provided can be used for any software you are looking to uninstall that is not listed under Add/Remove programs. Just follow the steps as such: Get the product GUID from WMI (Win32_Product class) Find the GUID related to the product or products that the SQL error mentions Run MSIEXEC /X {GUID} for each of the products to uninstall them manually. http://jermsmit.com/uninstall-of-sql-fails-with-error-about-rsfx-driver/
