Plextormanager 2000 install

This was my experience. The install went fine, but then launching
Manager from tray, start menu, or explorer brought the system to a
near standstill. If i CTRL|ALT|DEL and kill any of the Manager
processes (plxstart, plxtask, A2K, M2K, V2K -- if i recall) which are
running, then the system returns to normal.

I have never installed MP7, but have the same problem as you.

I may have the answer for uninstall:
1. CTRL|ALT|DEL and end all Plextor processes. Every time you try to
uninstall, more processes get started. You have to clean them out
every time you reboot or try unsuccesfully to uninstall.
2. In Add/Remove Programs, remove Manager.
3. IMMEDIATELY you need to use CTRL|ALT|DEL to kill the Manager
processes that are started. If they get hold of the system, the
uninstall hangs.
4. If you get a message that the uninstall can't proceed bacause file
DelsL.isu can't be found, reinstall Manager over itself. If you can't
launch the install from the Manager2000 installation window, open the
CD in Explorer and run Plextor\Pm2k\setup.exe to reinstall.
5. Remove Manager.

You may have to try several times to get the right timing. The trick
is to get the Remove going and then catch it before it launches the
Manager processes and uses them. When you successfully catch them
all, the uninstall will proceed normally. You should be left with an
empty (or near empty) Program Files\Plextor2000 folder and an empty
folder in your Start Menu.

Let me know if this works. I haven't found a workaround yet that will
let me install Manager and have functionality. On one of my many
installs, it all worked. Then, on the next boot, it was back to
stalling again. Have no clue why it worked that one time (not the
first).

And, I have a second problem. After my secondary IDE channel
recognized the 16/10/40A as master, and I enabled DMA, I lost the
channel. Can't use it for CDROM or harddrive. If it boots, no
devices show up in Device Manager, so I can't disable the DMA, if it
is indeed still enabled.

I have the exact same experience with W98SE and a new 16/10/40A with
the retail software. Manager locked up during uninstall. I
reinstalled without incident. The system degraded to unusable. I
succeeded in removing EZCD403 and DirectCD, but Manager uninstall
locked. Thereafter, the message says can't find the uninstall file.
Neither will it reinstall.

Plexstart and Plextask still show up as running at after bootup, and
unless I kill them both the system protests or crashes. The icon in
the tray won't launch it.

Ditto your experience on the ASPI layer check and messages.

With Manager neither launchable, reinstallable, nor uninstalled, and
with the system so compromised, I might as well have an onboard virus.
Hope you get some help and that I can tag along.
