Suddenly a problem to compile to a hex file (error code 120)

Dear mr, mrs ,

Please help, I use Windows 10 x 64 using Flowcode 4 and Flowcode 6 both.
Until a few days ago, I had no any trouble whatsoever compiling a flowchart in FlowCode 4 into a hex file and writing it to a PIC via the EB-006-00-7 board. However, I’m now suddenly getting the persistent error message “Compiler cannot be started without a host program (code 120)”.
I am now getting the same error in FlowCode6 as well.
I have had a quick look at the Compiler options section and cannot see anything unusual, such as empty fields.
What can I do to resolve this issue, as it is currently impossible to create a hex file?

Many thanks in advance for your support .’

Kind regards,

Reinier Ott

Dear Steve,

Thanks a lot for your answer and I read your linked posts.
As mentioned, I did solute this problem by removing FC4 and re-installing. :D
(Before, I tried the option "Repair" of the installation, but that does not had effects)

Thanks
