Dear Manu-I,
With MFCOM, the BrowserName property is ReadOnly, so it can't be set when importing the Published Resource.
XenApp App Export Manager is handling the MFCOM BrowserName2 property which is Read/Write.
However we can try to investigate this issue (which is more an MFCOM limitation than an issue) and try to find a workaround.
Best Regards,
Pierre
