Can i reinstall 4.1 and remove 4.2

i use imac i7, 8GB, Lion.
i installed LR4.2 (after LR4.1). I am disatisfied with 4.2 for number of reasons.
can i reinstall 4.1 and continue to use my prwesent catalog?

geoff,
thanks for your interest. i have the latest mac drivers, i suppose.
i had problems with occasional "flashing" of image, following adjustment slider action, on 4.1, but this was limited to TIF.
With 4.2, I had a delay of 2-4 seconds during which I had a black image window, the rest of the interface remained as it should be. This "flashing" only happened in develop mode and ocurred after each slider movement, regardless of amount of adjustment, and it affected jpg,psd, and tif. very annoying.
I installed 4.2 update over 4.1 without difficulty.
my iMac has an i7 CPU, 8GB ram and I use Lion 10.7.5.
Hope this will trigger a memory or something that might help because I do have trouble with the clarity slider in 4.1 and this apperas to have been fixed in 4.2.
i will monitor to see if you've any suggestions.
thanks again,
vince

Contact your carrier and the police. If it was lost in a specific building, ask the people running it.

If I temporarily enable cookies at a website's request, can I then block it and remove the cookies which I allowed.

I am trying to open a VULU account to rent movies. It requires that I select "Never Block Cookies ..." in my Personal Preferences so they can access my information.
Can I then go back and remove their cookie and restore the block without voiding my account?
I understand the purpose of cookies, but not much beyond that. Why do some sites require this to open an account?

Yes.

How can i uninstall Windows 7 and remove the partition?

how can i uninstall Windows 7 and remove the partition? white unibody late 2009. i cannot seem to find bootcamp either :/

Open the Boot Camp Assistant in the /Applications/Utilities/ folder and use it to restore the drive to a single partition setup. If it's not there, use Pacifist to extract it from your install DVD and run the combo updater for your OS version.

Can I reinstall mountain lion and do away with Mavericks

Can I reinstall from aps mountian lion and do away with Mavericks? I do not like Mavericks at all.

Should be able to - problem is, Apple said they wouldn't be updating any of the older versions anymore - so any security issues may remain unpatched.

Can I reinstall last month and then change back if needed?

If I select my HD and reinstall back from say January 1 and it does not solve my problem can I reinstall yesterday and get everything as it is yesterday. I guess also that it will take a long time like the first time it backed up.
I have a program for wireless printers and for some reason the software worked for one or two days and not upon opening says "SXUPTP Driver has not been installed. Please install the application again."
I am trying to get back to when it worked and don't really know what the problem is. But I have installed it on another MacBook and it works fine. So it something in mine.
Thanks

I've found that out but this software from Sitex is suppose to install that driver in the right place and for some reason it does not. I have been in contact with their technical people and they have not figured it out so far. They are now going to Japan which is their engineering I guess.
See I have Fusion with XP also and this software is supposed to handle all of it. It works fine with the PC here. Worked for a day or two on the mac also then quit.

How can I clean a mailbox and remove all but the latest message in thread, and more...

I am using Thunderbird version 24.6.0, for years I have been saving every email into a mailbox folder of a technical email alias I subscribe to.
The folder now has over 12,000 emails and I am exceeding 700 MB. Is there an Addon or tool of any kind that allows me to automatically in one fell swoop delete all but the last message in a thread assuming all prior messages included all prior messages in thread, BUT here's the hitch, if someone responded out of order to a thread or did not include prior messages, their message should be saved since it will not appear in the prior string of messages.
I can draw it out better than explain it, I want to save all responses to a thread, except those that are captured by the final message in a thread, or....
| Re:- topic1 a. don't save because all included in "c"
|- Re: topic1 b. don't save because all included in "c"
|- Re:topic1 c. save
| Re:- topic1 d. don't save because included in e.
|- Re: topic1 e. save
Thanks! ed

I have no idea on how, but your file needs to exceed 4Gb before there will be any kind of issue (and the guys think they have removed that limit not anyway)
Thunderbird will not move slowly or anything with lots of messages.

How can I reinstall "lost" Safari and Camera functions?

Ever since I dropped the phone a week ago (still working otherwise), the Safari and Camera icons have disappeared from my home screen, and I cannot seem to find them.
I have tried "Reset Home Screen Layout" from the Settings / General menu, but while the existing icons rearrange the missing ones do not appear. I would like to restore these icons if possible, but I am not sure how to do it myself.
As I am a relatively new user, I am probably missing something, but I couldn't find it on a few searches for the information.

Check Setting->General->Restrictions. If restrictions are enabled, the icon is removed from the home screen.

HT2703 Can i reinstall Bonjour without uninstalling/reinstalling itunes after accidental removal?

Can i reinstall Bonjour,after accidental removal, without uninstall/reinstalling itunes?

Uninstalling and then reinstalling your iTunes should also get your Bonjour reinstalled.
For the reinstall, use an installer downloaded from the Apple website:
http://www.apple.com/itunes/download/
... or you could get it back via your Apple Software Update for Windows.
If you'd prefer not to uninstall iTunes, try the following procedure.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the Bonjour.msi (or Bonjour64.msi) to do a standalone Bonjour install.

Set-acl and remove-ntfs both fail from PowerShell yet i can do it from the GUI

I have put together a script that searches all of our folders then searches the folders for groups that should have access and do not and groups that should not have access and do.
Finding only the folders that need NTFS permissions changed works great. Adding the groups that need added works great but removing groups is not working. Below is a section of my script with the section not working underlined. You can
see i have tried 2 approaches.
If i use the Remove-NTFSAccess command (which i really prefer) I get no errors and you would think all worked until you check.
If i use set-acl about half give me a error "Set-Acl : The process does not possess the 'SeSecurityPrivilege' privilege which is required for this operation" but it does not remove the Domain admins for any of the
folders including the ones that give no error.
I have privileges to do it. I can go to a folder and remove the group from the NTFS permissions in the GUI with no issue.
Thanks!
"Add Nseries Admins"

$acl=get-acl "$path"
$accessrule = New-Object system.security.AccessControl.FileSystemAccessRule("SCHOOLS\Domain Admins","Read",,,"Allow")
$acl.RemoveAccessRuleAll($accessrule)
Set-Acl -Path "$path" -AclObject $acl

I just ran that a couple of times. No errors as long as the subfolders are not protected in a way the blocks the admin. I will try and find a folder that causes this exact scenario.
Is it possible that this was fixed in V4?
¯\_(ツ)_/¯
The SACL being overwritten isn't fixed. There's a Connect bug
here. Set-Acl basically does this before trying to call SetAccessControl():
$path = "$env:Temp\temp_item_name"
$acl = Get-Acl $path
# Get the binary form:
$binaryForm = $acl.GetSecurityDescriptorBinaryForm()
# Create a new SD object:
$newacl = New-Object $acl.GetType()
# Take the old binary form and use it for the new SD object,
# but tell it it's for all sections, including the SACL:
$newacl.SetSecurityDescriptorBinaryForm($binaryForm, "All")
Next, it tries to call SetAccessControl() inside of a try{} block. If it detects a PrivilegeNotHeld exception, it will try to redo the section above without setting the Owner, Group, and SACL (if certain conditions are met). I can't get the second call to
error the way Lishron did, but that doesn't mean there's no scenario where that can't happen.
By the way, here's an example of trying to call SetAccessControl() with the modified SD object from above:
$FileSystemItem = Get-Item $path
$FileSystemItem.SetAccessControl($newacl) # <-- Fails if you're not an admin; overwrites SACL if you are
$FileSystemItem.SetAccessControl($acl) # <-- Succeeds (unless you're trying to change the owner)

How can i reinstall cd/dvd drive - Satellite P100 PSPAD

Hi
I have Satellite P100 (PSPAD), and my cd/dvd drive (I dont know how or when) suddenly disappeard, it does not appear in my computer or device manager,
I tried this but coul not find the lowerfilters so i delite the upperfilter and restart the computer but that did not work.
So can I reinstall it somehow and how do i do it?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Caution There can be many instances of the registry subkey that is mentioned in step 2.
You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values.
To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.
3. In the right pane, right-click UpperFilters, and then click Delete.
4. Click Yes to confirm the removal of the UpperFilters registry entry.
5. In the right pane, right-click LowerFilters, and then click Delete.
6. Click Yes to confirm the removal of the LowerFilters registry entry.
7. Exit Registry Editor, and then restart the computer.

Hi guys
Just one question;
Are you able to boot from the bootable disk like Toshiba recovery disk, Windows XP CD, Vista DVD or Linux live CD???
If yes, then you should try to reinstall the OS.
If not then this would mean that the CD/DVD drive malfunctions.
*@BlackJack_1*
You said the CD/DVD drive has been recognized by BIOS.
Do you see the whole CD/DVD drive title/name or you can see just the CD/DVD drive option.
You should also test if you can boot from one of the mentioned disk and to ensure that this is not a hardware issue!
