Application of support packs stuck

Hi

I am in the process of applying the support packs for my NW 7.3 for BPC 10.0.

I've applied the first basis patch sp01,  however it has been running for the past 5 hours now in the phase Main Import.

Please if you can help in finding out what the problem could be.

Environment :

Win 2012 R2

Oracle

NW 7.3

Cheers

Nitin
