K3.lic error even before the expiry date

Hi All,

I Have installed Appian in my machine, I am having the Temporary License file k3 valid till oct 4,

I have done installing Appian and clearing it and again installing for many times in one machine probably 4 to 5 times due to lots of errors,

Now the thing is I got the license file again and trying to install in the same machine,the k.exe file is throwing me an error

k3.lic

Is there any issue in uninstalling the Appian and installing it.

Please advice.

TIA :)
