Problem with XML import MDM 7.1 SP2 u2013 XSD.exe Issue

We are upgrading MDM from 5.5 SP6 to 7.1 and currently we are in SP2 but will be upgrading to SP4 soon.

After upgrading to MDM 7.1 SP2, when we use the import Manager and try to import the XML file we got the following error message Can't open C:/Program files/SAP MDM 7.1/Import Manager/XSD.exe.

My question is this error is only with MDM 7.1 SP2?. In few days we will be upgrading to SP4. In SP4, this issue is still there?. If Yes, How to resolve this problem?.

Anyone can send me the XSD.exe file ?
