Installation of eScan Anti-Virus

We installed a trail version of eScan Total Security for Business Anti-Virus on 3 client computers about a month ago. We informed the customer that they should enjoy the free 30-day trial version and we would provide license keys at the end of the 30 -day period.

We got the license keys from eScan and planned to go to the client to update the license from trial to a full one-year valid anti-virus protection. The customer was happy that I had come to complete the job. They provided 2 out of the 3 laptops to me to begin the update.

I powered on the first laptops and when i opened the eScan application to insert the keys manually, I noticed that but the feature ‘License Information’ was disabled. I tried many means of resolving this by clicking on one feature to another but it still didn’t work out, so I reported this situation to eScan TAC Support.

They decided to take remote control of the PC. TeamViewer access was given to the tech I spoke to. It took him two to three minutes moving the mouse cursor from one feature to another then later informed me that since the trial period was over for some time the license cannot be updated, and that the AV would have to be uninstalled completely and a new AV would have to be downloaded and installed.

A link was sent to download; They sent a different version of eScan (Total Security Solution for Windows). We downloaded and copied the setup file of the application on a USB drive, uninstalled the AV from the control panel and restarted the laptop. The installation ran smooth and the license keys were accepted which shows 1-year validation period. A full system scan was carried out on the laptop and turned over to the end user.

I moved out to the next laptop. I did not uninstall the old AV app instead used the new setup to detect and uninstall. During this process, the laptop shutdown by itself due to low battery. The end user brought the power adaptor and connected it to the laptop. I then powered it on but the old setup was not showing in the control panel. I ran the new setup file but it kept prompting to uninstall old app. I restarted the laptop again but still it didn’t work. We could not get the old app to completely uninstall from the computer.

We then checked the app directories to see if there any patches of the old app left. A few patches were found in the system, in application folder.

We tried several ideas to uninstall the AV but were unsuccessful. There was no solution found online as well.

Then we decided to use the Windows Command Prompt which is last option for resolving Windows issues sometimes. Here are the few steps shown below that was used to solve this issue.

Opened Windows CMD by administrator by typing 'Windows key +R.'

Typed ‘dir’ and hit 'enter'. This allows you to see all installed app in the system.

Typed ‘escan’ and 'enter'

Typed unis000.exe and hit 'enter'

The uninstallation progress was displayed and gradually the remaining patches were successfully uninstalled. We then installed the downloaded eScan Total Security for Windows, and activated the license keys.

I was glad that the customer had that patience to wait and see the installation ending with success. 

This was tested and was working well after running full system scan in the customer’s midst.

They have informed me that their other colleague will be back anytime soon to have the 3rd PC activated. I can clearly say the other PC will take me less than two minutes from this experience I had.

Another happy NATC customer! Another day of learning and improving our knowledge base!
