1.18a failed to update


I tried to upgrade VeraCrypt 1.17 to 1.18a using the windows exe file. It failed to install/update the program and I had to install 1.17 to be able to use the program again.

What error did you get during the upgrade?

What version of Windows are you running on your PC?

Did you disable your Anti-Virus software before the upgrade?

The program simply failed to install the upgrade. It simply said "installation failed" or something to that effect.

I am using Windows Vista. My Anti-Virus software wasn't disabled prior to installation.

Are you running 32-bit or 64-bit OS?

Are you using system encryption?

Try the VeraCrypt upgrade with your Anti-Virus disabled or uninstalled during the upgrade.

32-bit OS, no encryption.

I've got the same Problem subscribed above: Windows Vista 32-bit, no encryption, Avast AntiVir disabled during installation. No chance to install VeraCrypt 1.18a. Version 1.17 installs without any problem.

Hi, same problem with me here, running Vista and Windows Security essentials.
Veracrypt 1.17 installs no problems.
At 1.18 and 1.19, I get "Installation Failed" and here is the sequence of events:
-Installing Veracrypt decive driver
-Starting Veracrypt device driver
-adding icon ... Veracrypt.lnk
-The installation has been rolled back

Same issue here, but first not on Vista it seems.

Win Server 2008 Std (32 bit), AV = McAfee (enabled), existing encrypted partition.

Slight backstory...

TrueCrypt to VeraCrypt update.
Managed to get through TC 7.1a to VC 1.0f-2.
Tried to update that to 1.19 - FAIL - auto roll-back (per Bastnja's comment above)
Try instead to 1.18 - FAIL (same again).
Try 1.17 - SUCCESS.
Then from 1.17, unable to update to anything newer (same issue again).

We're probably not going to be able to use this if a future update doesn't fix the install bug with newer versions, unfortunately.
