For some time now, I haven't been able to open the Galaxy client. I get a series of GalaxyClient.exe errors. They are:

MSVCP140.dll not found
VCRuntime140.dll not found

I noticed that this happens with the EA origins client as well, but Steam, UPLay, and Epic games launcher all work.
Latest version of windows 10 is installed.

Is this something new? As in, did Galaxy use to open previously, but now it doesn't?

Anyway, it looks like you need to install Microsoft Visual C++ 2015 Redistributable Update 3 RC. Here is Microsoft's official link:
https://www.microsoft.com/en-us/download/details.aspx?id=52685

You should only need to install the x64 version.

That doesn't seem to work - it says a newer version is installed. I've got Visual C++ versions 2006, 2008, 2010, 2012, 2013, and 2017. It has worked for the last 2 years so I am not sure what happened all of a sudden.

If you have the redistributable for c++ 2015 already installed you should try this:

1. Click the start button, and type cmd
2. Right-click on the Command Prompt App, and and select Run as Administrator
3. Paste the following and press ENTER:
regsvr32 /u VCRUNTIME140.dll

4. Paste the following and press ENTER:
regsvr32 VCRUNTIME140.dll

5. Paste the following and press ENTER:
regsvr32 /u MSVCP140.dll

6. Paste the following and press ENTER:
regsvr32 MSVCP140.dll

7. Try to see if Galaxy works now.

I'm thinking the /u in the last command shouldn't be there, unless you intended to unregister the DLL twice.

Of course... fixed.

Sorry for disappearing, had a busy week -- I tried all of those and they basically all came back with an error saying:

"The module 'VCRUNTIME140.dll' was loaded by the entry-point DLLUnregisterserver was not found. Make sure that 'VCRUNTIME140.dll' is a valid DLL or OCX file and then try again."

Just substitute the VCRUNtime with the various dll names for those particular errors. I've tried running an SFC scan as well as a DISM thingy to see if there is any corruption in windows and nothing popped.
