Help! Installed Panther and upgraded to 10.4.3 and cannot reply to emails

Hi,
Just installed to Panther a few days ago and yesterday I downloaded the 10.4.3 upgrade and now nothing happens when I hit "reply" to a mail message. Also, if I hit "forward" or "compose" the proper window opens up but I can't type more than a few characters or delete what little I get to type.
Any help/info will be greatly appreciated.

I submitted the above question, later finding that it has been answered by Buller already. No one need reply as Buller's answer seems to solve the problem for others, and I'll try that.

I need help installing InDesign CS6 upgrade because on this new computer I cannot install the version that it was upgraded from.

Stevel18 you can install the upgrade to Creative Suite 6 directly. During the installation process you will be asked to enter the serial number of the product which qualifies you to own the upgrade.

...AppleACPILPC.kext" was installed improperly and cannot be used

I've recently been cleaning up my machine after upgrading to leopard. I've fixed most issues but this is still a problem:
every time I start up, I get an error box with an orange triangle exclamation point and this message:
The system extension "/System/Library/Extensions/AppleACPIPlatform.kext/Contents/Plugins/AppleACPILP C.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
I was going to do a re-install, but since I've already upped to 10.5.1, it didn't give me the upgrade option, and I'm not sure I should try another way. Especially since this is the last of about 11 of these boxes which still appears, the rest of which I've been troubleshooting individually.
I did search my loepard install for the extension, and replaced the one in my system folder with the disk's version, but I still have the problem.
I don't know if this is causing any real trouble, but I do have one major problem to resolve, to which this one may be contributing, so I'd like to resolve this, or at least hear that it doesn't matter.
the big problem is that my Access Virus TI keyboard isn't recognized half the time and even its AU plug "virus Control" can't communicate with it.. even the software installer (during re-install) can't communicate with it!
But I'll post that elsewhere.
Please, if someone could help with the extension issue, I'd really appreciate it.
Thanks
Dan

I get the same message
I have been trying to resolve an issue with my upgrade where I have to enter a password to do anything with the files on my desktop. I followed an apple procedure to reset my admin permission [which did not work], but now am getting the same message as you plus one for
/system/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/Appleyukon.k ext
When I track it down in the finder, the "IONetworkingFamily.kext is not a folder as far as I can see so cannot ft to the contents, etc.
What are these things? What happens if they are not installed and how do I fix this since I do not want to reinstall either. And what is a "Kext"?

Trying to reinstall Canon MX882 printer, I get the message /System/Library/Extensions/AppleUSBEthernetHost.kext installed improperly and cannot be used.Try reinstalling or contact vendor for update. Where is this and what do I do/

Trying to reinstall MX882 Canon printer after upgrading to OSX Mavericks. Printer will not print and I get a message "The system extension "/System/Library/

What do I do and where is this extension?

I would recommend you download and install the OS X 10.9.5 Combo Update.
That file is part of the operating system and it is located where the error shows, i.e. HD > System > Library > Extensions. It would seem that when you updated, this file and maybe others have not updated correctly. So running the Combo Update may help resolve this.

Hopefully, i can get some help in resloving the issue below. i updated my harddrive at Techserve and have been getting this message evertime i try to install a new software. Help...
The system extension “/System/Library/Extensions/CDSDAudioCaptureSupport.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

That is a third-party extension, so I would reinstall that software unless you wish to try repairing the permissions on the extension yourself using the Terminal.

thanks for the helps.

Need to google WkClassicNotSeizeDriver.kext to find out exactly what this is but I don't think it's an apple kext so remove it.
/System/Library/Extensions/WkClassicNotSeizeDriver.kext
After removal reboot. That reboot will take a little longer since the kext cache needs rebuilding.
Update:
Google search found the following thread:
WkClassicNotSeizeDriver.kext ??? under 10.6
Googling "WkClassicNotSeizeDriver.kext" didn't turn up anything really definitive as to where this really came from but it did show others have seen that same kext. Just trash it.

In running the Software Updater, I encountered an error: "System Extension cannot be used" ... System/Library/Extensions/AppleUSBEthernetHost.kext was installed improperly and cannot be used.

While running the Software Updater, I encountered an error: "System Extension cannot be used" ... System/Library/Extensions/AppleUSBEthernetHost.kext was installed improperly and cannot be used. Can somebody help me resolve this error message. Would this error affect my ability to run FaceTime ?

Seems pretty clear to me. Here's what you can try:
Open Terminal in your Utilities folder. Paste the following at the prompt:
sudo chown -R root:wheel /System/Library/Extensions/AppleUSBEthernetHost.kext
Press RETURN. Enter admin password when prompted. It will not be echoed so type carefully. Press RETURN again.
Restart the computer.

How do you fix the error - "The system extension "/System/Library/Extensions/IOBDStorageFamily.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."

I have started getting this error every time I download anything to my computer. I want to know how to fix the issue so it dosen't happen anymore. The error is as follows:
The system extension “/System/Library/Extensions/IOBDStorageFamily.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.
Please help me.

Darned drivers. Did you try using it without the drivers? They may already be in Mountain Lion. I'm super wary of vendor drivers for OS X; they're terrible and often an OS version out of date.
To re-install OS X, log into the Mac App Store, go to "purchased," re-download Mountain Lion, and double click "Install Mountain Lion" as you did the first time. You won't lose data (have a backup!) and an hour later you should be good to go.
After that, try using the printer WITHOUT installing the darned Lexmark drivers.

What is this error message about, "The system extension "/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt" was installed improperly and cannot be used"?

It appears as a window with the following text, "System extension cannot be used. The system extension “/Library/Frameworks/PrivateTunnel.framework/Versions/Current/Extensions/tap.ke xt” was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update."
I close it by clicking "Ok", and it doesn't seem to affect the system performance in any way, but it's annoying knowing that it's there. The problem is quite old, and has persisted through several OSX updates.

hello,
I have the same problem. does anyone have any ideas on what's going on and or how to fix it.
Thanks!!
Luis

You don't even have to type more than 8 letters:

What does this mean? ... System extension cannot be used ... The system extension "/System/Library/Extensions/IOFireWireWDHID.kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

I get this message often when updating things. I have told Small Dog Computer where I buy my stuff, and they didn't have an answer. Thanks in advance.

Interesting ... thank you! Actually I had that external drive, Western Digital, a while back on my second last? or third last? laptop ... the external drive died with a slew of pictures I had carefully uploaded to it :-(
I won't worry about it anymore :-)
sorry you got only 5 points, can't figure how to give you 10 points.
