Hi

5.1.2.0.5.007 has been superseded by 5.1.3.0.5.003, so 5.1.2 is not available.

*Look for 5.1.2.0.5.007, it should mention that it's superseded.

So you can only download 5.1.3 or above.

thank you for reply.

i have another question it's possible to revert to previous version (downgrade).

if yes, its the same procedure for the upgrade?

Hello, Can you please let us know the reason of upgrading and then again downgrade?

1. Issue in the system?

2. Sync problem?

3. System error ?
