Issues in Installing Web AS - Java [ FSL-02077 File system export (share)]

I have installed ABAP Web As - 2004s on my laptop.

I want to intall JAVA Web AS as well. How ever, when I try to install the JAVA Web AS,

It is failing with the following Error:

FSL-02077 File system export (share) saploc does not exist.

it happens after I agree the licence, enter the right JDk version and enter the Permissions file.

I am running on XP Home Edition,

No Fire walls running

No Anti Virus software [ infact I uninstalled it]

No Ports are in use [as per Pre Reqs]

User has the Administrator access

Any insights ... Please ...
