One solution for one set of circumstances: Momentum Cache would not fully install for me with my new MX300 SSD. I tried the recommended solution of uninstalling then reinstalling (meaning starting from scratch with Storage Executive, completely reinstalling it, including Momentum Cache), BUT Momentum Cache would not fully install. After much perseverance (meaning repeating the reinstall process a few more times with one minor variation where I rebooted my PC after the uninstall but before the re-install) that met with repeated failure I gave up and sent in a Customer Support request (but not even Crucial's Customer Support report page within Storage Executive would work properly--it froze at the point where I agreed to allow Crucial Customer Support to proceed with automatically collecting 4 log files from my PC--very frustrating). Next day (today) I happened to notice that my Windows 10 (version 1703 build 15063) Credentials Manager control panel would not open (some how its service file within the services folder was disabled??? ...I reenabled it and it returned to normal)... Then I wondered if anything else in my system had been changed lately... by lately I mean during the beginning of my recently installing my Crucial SSD. The only thing I could think of was that when transferring my OS from my hard drive to the SSD (which went well) the two partions created by the software I used to do the transfer (MiniTool's Partition Magic-free edition) were automatically named System (G) and Windows (C). NORMALLY the System partion does not have a letter assigned to it which thereby keeps this small partition hidden (meaning not being listed within any window file directory) ...So I went back into Partition Magic and changed the partition letter to "none"...then I reattempted to install Momentum Cache and it finally installed! I don't understand how turning Credential Manager's service back on might have been part of the solution, but I can easily understand how Momentum Storage's installation software might have expected the system partition NOT to have a letter assigned to it and so got hung-up trying to find my PC's unlettered system partition when my system partition was in fact named: System X (where X stands for any letter). I hope Crucial sees this message and incorporates it as a troubleshooting footnote within the future editions of their SSD installation instructions. I will try to email them a copy of this. Hopefully their Customer Support report page is working, but its the weekend so first I'm posting this here for possibly quicker access by anyone else dealing with this very frustrating problem.
