Cannot understand the error 'The type Initializer for CrystalDecisions.Shared.Sharedutils threw an exception'

Hi,

On my windows 7 64 bit Development Pc with .net4 framework installed, I have developed a desktop app using visual studio 2010, SQL Express 2008 and I used crystal reports for printing purposes.

Whilst printing, On the development machine all reports print perfectly (with a few exceptions),

however on deployment machine, the app works great but when printing I get the error

'The type Initializer for CrystalDecisions.Shared.Sharedutils threw an exception'

This happens on all deployment PC's including windows 10 tablets.

I have installed the support pack 13 (v.13.0.13.1597) on development machine,

and I have attempted to install the MSI's on the deployment machine but to no avail.

all help is greatly appreciated.
