I was able to install ToolTipTool NT 20190819 under Wine in Linux; It requires mfc42.dll installed in order to register with regsvr.
However, I do get the following error when executing the software:
Report the following: VALUE ERROR TXBar9[93] b ⎕wi 'list' ('-' Before ¨ Speak 'Voices') ^ _________________________________________________________________ TXBar9[93] * TxCtrl[135] Start[85]
It does startup; testing it to see if can successfully create modules is another matter.
