Though I had sworn not to install any programme other than using the Synaptic, I had to break it because I had to install a Windows based programme, through Wine.
I installed IrfanView image editor on my LM 17 Qiana Cinnamon through Wine. Before doing that, I had to place the mfc42.dll file in the system folder of the Wine c: drive. But once I completed the installation, my 'Menu' got disrupted. Here is below what it looks like now;
The very few items that are visible on the left column now [earlier all the programmes were available] are not at all responsive. Nothing happens if I click on them. The items on the RHS are responsive.
One more thing that I have to inform is; initially I accidentally downloaded a non-english [I can't discern which language it is] installer package of IrfanView and installed it. But when I realised the mistake I downloaded the English package and installed. But the English version does not open. When I click on the IrfanView shortcut on the desktop, the non-english version opens. Now I was unable to uninstall the non-english version, because I cannot open Wine. It's icon has disappeared from the menu. I tried to open it with Terminal. Here is below what I get in the terminal;
Though I have the administrator privileges, it says you are not the owner.
I tried to Uninstall IrfanView with a third party Uninstaller [Iobit Uninstaller] in wine. I suppose, IrfanView got uninstalled, the program does not open when I click on the shortcuts now.
But I am still unable to open any programs now through the menu. I have to open them through the Shell. I could just open the Gedit. I don't know the commands for other programmes. So I don't know if they can be started.
I am in a mess. Please help me resolve this issue.
