Hi Kate
There is definitely such issue. This is a highly critical bug and Microsoft has to provide a patch.
We encountered the problem with one of our customers who installed our .NET application server for our Campus Management software on a Windows
Server 2012 R2.
Conversion from a string, e.g. 5.6 to decimal value failes. This is highly critical (imagine what happens
with financial applications). Changing sDecimal from "," to "." in the registry solved the problem. We have to inform all our customers in Switzerland about this issue and provide a workaround.
We reproduced this issue in our test environment by installing Windows Server 2012 R2. ISO file was downloaded
from MSDN subcriptions. Under "Customize Format" you can see that the decimal symbol is ",". Which is wrong.
