How can we tell what version has been installed?
The patch and version of the software is announced on the Logon Screen.
Again within the product you can check the version by going to My CRM> Preferences and clicking the About CRM button.
The version can be checked programmatically. This becomes very important where we need to be able to take into account changes in data model between versions.
In the COM Environment the version can be read from the System Parameters table (custom_sysparams).
In code using the Web Service the version can be read like this:
getversionstringresult CRMVersion = myCRM.getversionstring();
string strCRMVersion = CRMVersion.versionstring();
In the .NET API the version can be read using
string strVersion = Dispatch.Version;
