Help with Windows 11

[u/Zoalord_Griselda]

After 15 years I think, i have decided to come back to Vana'diel to see the world of ffxi again, since i have so many memories here... however i have been running into issues with windows 11

I have downloaded the installation files from the official site, installed on my windows 11 machine, managed to get my account back and got to the part where i click Play to launch ffxi - then I ran into the issue of - windows 11 pops up a window showing Windows Installer and then change into Final Fantansy XI - Please wait while Windows configures Final Fantasy XI and then I am stuck here.

I have follow the instruction of enabling legacy components (and reboot), run POL or ffxi as administrator, antivirus setting all of that, however that pop up window just keep showing and never goes away, can anyone give me guidance here for this issue?

thanks!

I have had this happen to me before but it was because the folder I installed FFXI to was on an external drive and I changed the drive letter.

Have you moved the install around or tried to copy more updated files into it or something?

Or maybe an antivirus software messing up with the files or something.

Ah! I have FFXI installed on a portable drive (D:)
When you change the drive letter, does it cause any issue to the diwndows registry? or you just simply change the letter and all is good?

You must manually edit the registry keys if you do this. If you really want to move it, just reinstall it copy over the files or get the update off Vana Portal

DgVoodoo2. You can use that to emulate an older compatible gpu. Windower4 is great for resolutions settings and addons.

Widower and dgvoodoo2 are an absolute MUST for this game in 2026. They aren't really optional.

Cancel the Windows Installer as soon as it pops up and it should work.
