software setup problems

Sometimes there are some antivirus software installed on a PC. Some do not allow setup and either they ask your permission or just do not allow setup and do not warn about it.

Once it was giving message that could not register a particular dll or ocx.

Possible ways are.

- Just temporarily disable the antivirus.

I did disable the antivirus(Kaspersky in this)

However the problem continued.

When I checked kaspersky it showed that license had expired.

So I uninstalled kaspersky. Then restarted the PC.

Then I tried to setup again. It went smoothly.

Note: check if any antivirus is obstructing the process.
