The Arduino Pro Micro Hookup Guide is badly out of date. It says “It should be a folder named ‘SFE32U4_Drivers’.” but the repo has changed since and there is no folder with that name. I found an inf online called “sparkfun.inf” but when I use that he says “the folder you specified doesn’t contain a compatible software driver for your device. if the folder contains a driver, make sure it is designed to work with Windows for x64-based systems”.
I tried the tutorial on how to hook up the Pro Micro but the drivers that is downloaded from GittHub that is supposed to be signed fails installing. There is a error about a hash missing or file corrupt.
I run windows 8.1 x64.
Could you please verify that the drivers are working.

I also have this problem; can’t install the Pro Micro 5V/16 MHz on Windows XP 64bits, and get the same message. It seems that all the driver packs I tried have versions for XP 32bits and Vista 64bits; but not for XP 64bits.
The hash for this file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.
Tried numerous compatibility modes, etc with no luck.
I can’t use the one remaining Win7 system I have for code development, so I really need a driver for Win 8.1 and 10. Looks like it could just be a packaging issue but at this point all of my Pro Micros are useless.
SparkFun employees generally do not participate as much in the forum. It is a community forum and any help you receive here is mostly from other customers like yourselves.
I have always found SparkFun to be fairly responsive, but the thing to do is to email them at techsupport@sparkfun.com
THANK YOU!! It had not occurred to me to turn off signed driver enforcement (there is a lesson to be learned there…) and it’s really ironic that Sparkfun had the solution (workaround, really) all along. I just tried this on Win10/x64 and it works. Woot! The Windows UI for this is abysmal, but I made it through even though it looked at times like it was going to fail with all the required reboots).
Ironically, I had just come up with a workaround for this today (posed on github) where I forced Windows to think the ProMicro was an Arduino Micro, but I was advised that this hack would be inadvisable on a 3.3V ProMicro. So now, I have a solution that works for both. Thanks for taking the time to post this solution. Props…
I have the 5V/16MHz ProMicro. When I uploaded my 1st sketch to it from the Arduino IDE, I neglected to choose the "ATmega32U4 (5V, 16MHz) from the Tools > Processor: > [menu]. The 3V/8 MHz is the default.
This oversight caused me to “brick” my Pro-Micro!!
I had to go through a lengthy ‘voodoo ritual’ to bring it back from the dead. That was my ‘lesson learned’
Now that I am working with both 5V and 3.3V systems all the time, I am 100% positive that I will end up doing this myself in the near future. Can you share the voodoo formula?? I know how to do this for my ESP modules, but have not yet had to do it for an AVR chip. Thanks.
I heard back from Sparkfun Tech Spt today, and they sent me a different driver installer that works. Hopefully, they will not mind my sharing the solution with the forum. It’s on GoogleDrive, so download it while it’s still there:
I can’t reproduce the issue on any of my machines, but I’ve written a new driver that I’d love for some of you with issues to test. Anyone willing to test this new driver from SparkFun?
Thanks a lot! I’ve tested on a Win 7/x64 machine, so it’s sounding like this driver is at least as good as our current one. You were having issues on those systems before, would you say the issue is resolved?
