Hi!   
  
 FinalBuilder 8.0.0.2412 can’t even open a project any more, which worked fine with previous versions.   
  
 The error message shown is:   
  
 Error Loading Project File : Variable BuildNumber Is of Type Integer   
 Failed to set the value : Could not convert variant of   
 type (UnicodeString) into type (Int64)   
  
 Manually editing the file and changing “variabletype = btInteger” to “variabletype = btString” solved the problem, but we would like to know why this is happening at all.   
  
 This is a local variable of an action group. In a “Simple Maths” action, this variable is summed with an other variable, which is provided via command line.   
  
 Kind regards!

What version did it open in ok before?   
 What is the value it’s trying to set.   
 Please send the project file to [support@finalbuilder.com](mailto:support@finalbuilder.com) so we can see what the cause is.

Hi!   
  
 It works in all builds up until 2403, regression started in build 2412.   
  
 The problem can be reproduced with a simple project ([https://pastebin.com/Y7tYWJEQ](https://pastebin.com/Y7tYWJEQ))
