Retreive lost emails on Incredimail app with Flash player in 2021

You can take help of this tiny little utility - RecoveryTools IncrediMail Migrator to retrieve lost emails from Incredimail application. As Incredimail support is shutdown already so you have limited choice with you.

If you have Incredimail 2.5 can use eM ckient. It can convert files. https://www.emclient.com/?lang=en&_ga=2.87103195.2139643426.1614441048-2130051183.1614441048

My incredimal was version 2.0 and had to convert the emails manually, but with great support from eM Client.

To install IM run install_flash_player.exe and install_flash_player_ax.exe. Flash files are included to operate IM. For Win XP delete or rename the files in C:\WINDOWS\system32\Macromed\Flash (Flash32_32_0_0_445.ocx and FlashUtil32_32_0_0_445_ActiveX.exe)

Ocx and exe files older versions are renamed as deleted or renamed after which you can open IM with clock and notifier.

For Win 7 or later, replace and rename the files in C:\Windows\SysWOW64\Macromed\Flash\ Flash32_32_0_0_446.ocx and FlashUtil32_32_0_0_446_ActiveX.exe.

For Win 10 run (reinst_flash_w10.cmd)
