Hi,
During installation this notice appears : AutoIt Error Line 25133 (File "G:\install\winsource\grub2win.exe")
Error: Variable must be of type "Object". before installation fails. I'm having a difficult time finding a solution to booting Windows 10 on an nvme drive with a bios only Dell Percision. I had it working for some time with Clover, but a failed windows update has caused things to come apart.
Thanks.

Hi,

This may be caused by an incompatibility with the newest AutoIt version 3.3.18 compiler.
AutoIt is used to generate the Grub2Win .exe files.
Some older and BIOS machines have problems with 3.3.18 generated code.

I am now compiling the Grub2Win Legacy code using the previous AutoIt 3.3.16 compiler.

Please download the latest Grub2Win Legacy version 1.4.3.5 build 1004 or higher.
It contains the code from the older 3.3.16 compiler.

Available here https://sourceforge.net/projects/legacy.grub2win.p/files/

Please let me know if this works for you.

Thanks,

Dave
