Answer 2

When I upgraded from Rotativa 1.6.4 to 1.7.3 my PDF conversion on my website app stopped working and after running the wkhtmltopdf.exe on my production server I noticed it was having an issue with msvcp140.dll

Solution was to install Visual C++ Redistributable for Visual Studio 2015 https://www.microsoft.com/en-us/download/details.aspx?id=48145

Answer 4

As mentioned in the comments on the blog linked in the answer, you can just copy the 2 following dll files to the rotativa folder on the server if you don't want to / can't easily install things on the server.

msvcr120.dll
msvcp120.dll

If it's working locally, you should have the two dll files available already. You need the x86 versions, if you find x64 versions packaged with vs 2015 they don't work. I found the right versions here:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\x86\Microsoft.VC120.CRT

After upgrading to Rotativa 1.7.3 this no longer worked. I had to copy over some new dlls from visual studio 2017, i found them here this time:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x86\Microsoft.VC140.CRT

and i had to copy over

msvcp140.dll
vcruntime140.dll

Answer 5

The accepted answer almost worked for me. I was missing a newer version of the C++ redistributable so installing the old version didn't help.

The easiest way to find out what you are missing is to run wkhtmltopdf.exe manually. It will either give you console output (if working) or a message box about what's missing.

I was missing MSVCP140.dll, which is from the VS 2015 redist, available here: https://www.microsoft.com/en-gb/download/details.aspx?id=48145

Answer 6

I fixed my issue by updating the wkhtmltopdf files from the installer found here

Working flawlessly now!
