It seems that SAI was installed in the cache folder for web browser, each files in the cache folder are deleted regularly, therefore the SAI application file is deleted too, additionally applications in this cache folder are limited in execution because of Windows security protection.

When the SAI installer is started, The displayed 'SAI installation folder' points the installer's location, so if you run the installer directly from downloading link of web browser, the installer is located in the web browser's cache folder. In this case, of cource default installation folder points this cache folder, and if you continue installation without changing this location, SAI will be installed in the web browser's cache folder.

If you want to install SAI directly from web browser's link, please make sure to select the folder that you created yourself for these applications (for example C:\Tools\).
We recommend once downloading the installer as a local file and running this installer after copying to the folder that you want to install SAI.

Please download and install SAI again. If you already have SAI's license, please make sure to download and setup the license certificate file too.
