In particular.
Set Random Number Generator Seed = 46837722323
Set Variable DLLRESULT to
Set Random Number Generator Constants = 9999, 1000
Num1 = Generate Random Number (max value 10000)
Num2 = Generate Random Number (max value 10000)
This seems to ALWAYS return the same value.
Both Num1 and Num2 seem to always return 11000.
This was not the case in 5.0.
Bitwise And
CHECKNUM = 178956970 and 22000
In IA 5.0 this gave 160, as it should.
In IA 5.1 however it gives 178956970, which is incorrect.

Oh Dear, this means that all of our serial number validation code does not work, so nobody can install the software

Any Ideas?
Need help very soon on this as we are in the middle of a major release cycle.
Cheers
