While generating the pdf you may see this error. There are some basic steps you have to follow to remove this error.

Step 1:
 
Try to install  "Visual C++ Redistributable Packages" you may found those packages in microsoft site, very easily. 

Note : If your production server wont allow to install this package then find (MSVCP120.dll)
 
Step 2:  Once you have used the Rotativa pdf form nuget packaged manager you must have got some executable inside it. as shown in the below image
 
 
Step 3: If you try to use this application to execute itself and test the what error you are facing while creating the pdf, try this way, the actual error you will get it. 
  1. c:\inetpub\wwwroot\DummyProject\Rotativa\wkhtmltopdf.exe  d:\Pdf\Dummy.html d:\Pdf\Dummy.pdf  
After executing this line of code either you will get fresh pdf file or MSVCP120.dll missing error.
 
Step 4: This is the final stage you have to only place those dll inside the Rotativa folder which you are hosted in the IIS . If you are enable to execute the  Visual C++ Redistributable Packages in production server, no need to worry, Only just placed "MSVCP120.dll" inside the Rotative folder. This will work fine.
 
Summary
 
This article explains a common bug, when we try to upload our website in production server and we have used the Rotativa dll, this error might may occur. On this issue this method works.
