Multiple versions of Essential XlsIO

[Ram Thatikonda]

I have installed Essential Studio new version 9.1.0.20. One of my old application that uses the version 7.4.0.20 is not longer compiling. However, I could see both the version assemblies under C:\Program Files\Syncfusion\Essential Studio, but the GAC only has 9.1.0.20 assemblies.

How do I fix the error "The type or namespace name 'Syncfusion' could not be found (are you missing a using directive or an assembly reference?)" in my old application?

I would appreciate any guidance from Syncfusion.

Thanks!

I could fix this problem by adding the missing 7.4.0.20 assemblies to GAC using "Run Assembly Manager" tool.
