The Download Manager could not be installed on this computer
When attempting to download ProClarity Web Professional, you must first download an .exe file which installs a single .dll file. This .dll file, the download manager, helps determine which ProClarity products are installed on your client vs. which are available on the server. If you try to go through this process using the 64-bit version of Internet Explorer, you may receive an error, "The Download Manager could not be installed on this computer." You must use the 32-bit version of IE to complete this process.
