I am using Inno Setup to copy all entries in the registry from one location to another. Can you please advise on how to do this? Thanks.
There's no easy way to copy registry tree elsewhere.
You can use WinAPI RegCopyTree (but you will also need to import and use RegOpenKey, RegCreateKey and RegCloseKey).
If you want to stick with plain Pascal Script, you would have to use RegGetSubkeyNames and RegGetValueNames to collect all subkeys and values and copy/write them one-by-one.
For some example, see Copy32BitUninstallKeyTo64bit in Inno Setup: Keep existing 32-bit installation path for upgrades, use 64-bit path for new installations – though it does copy only all values (and of specific types only), not subkeys

I am trying to import .reg file which is exported from another system who is having same configuration. Is it possible? If it is possible what kind of problem i may face? Thanks in advance
It is very hard to answer this question in general.
If you only import a single key that contains no paths that are unique to the system where you exported, it will almost certainly work without problems.
Especially all keys that are basically settings will work most of the time.
If they keys contain paths that don't exist on the other systems, or information about registered dlls/ocx files that are not present it will most certainly not work.
Keep in mind that those .reg files are all just text files, so a good idea would probably be to export it, open it with a text editor and look at what subkeys are contained within if you are unsure.
Also make a backup on the new system before the import, so you can revert all changes later.
What methods exist to include parameters (such as userid) into the setup.exe that users download from a server?
I'm looking for a way to give a customized installer to users that I already know (because they are logged in).
Is your question tied with some technology/installation system? Or you are researching which installation system to use to achieve this functionality?
In NSIS there is option to append custom data to installer, see this article: http://nsis.sourceforge.net/ReadCustomerData.
Maybe the easiest would be to send a setup_whateverparameter.exe filename instead of setup.exe...
A smarter approach would probably be to store parameter into a ressource file which would be edited from command line with some tool like http://www.reseditor.com/
Another one would be to generate a sort of INI file which would be packed with the original setup file using some installer software like Inno Setup (http://www.jrsoftware.org/isinfo.php) and the original installer would be configured to check if some ini file exists in a temporary location, to just use its content to do specific tasks.
Other possibilities might exists, thoses are just the one which might be the most easy to implement.
#elfrancesco hinted at Ninite and Patrick from Ninite got back to me with:
We put the installer id in a segment of the .exe that doesn't get
included in the hash for the signature. So we just sign our loader
.exe once whenever we update it and then our web server drops in the
key for each download.
I was going through the source code of a rainmeter skin and i could not understand :

TextShortcut2=Libraries
TextShortcut3=Internet
TextShortcut4=Media Player
TextShortcut5=Control Panel

Can anyone tell me what

these are
and also how can we get one of these for a specific location from our computer.
Those are CLSID (Windows Class Identifiers). Certain special folders within the operating system are identified by unique strings.
20D04FE0-3AEA-1069-A2D8-08002B30309D is My Computer
21EC2020-3AEA-1069-A2DD-08002b30309d is Control Panel
645FF040-5081-101B-9F08-00AA002F954E is Recycle Bin

In response to the comment:
can i have Class Identifiers for any folder on Computer or is it just
the bunch of those.
There isn't much reason for you to add more clsids, since you can just go to other locations by typing the normal path. This is a set list that is in the registry somewhere for special folders that don't really have "paths" like C:\windows does.
what is "shell:Something" is it a cmd command or location
shell: is similar to above. It is a convenient way of accessing special folders. Here is a good site for a list: http://smallvoid.com/article/winnt-shell-keyword.html . It is more of a shortcut for Windows Explorer to access a specific location than it is a command. You cant use them in batch files as far as I know (no command line stuff).
what is %something% like %temp%
Those are environment variables. You can usually count on certain ones existing, but the user can change these. Here is a list of some more: http://en.wikipedia.org/wiki/Environment_variables#Microsoft_Windows
how do they all differ?
Well, basically, they are just different ways of accessing the same thing. Some things are more backwards compatible than others, so you have to make that choice when the time comes. If you know your app is going to be on Windows 7 and above, you can make use of some of the more convenient shell:something ones. But if it needs to run on Windows 2000, you might have to rely more on older stuff like environment variables. Environment variables can also be customized by the user.
I have an old update program written in vb6, which runs as admin. However, because it runs as admin, all the files it downloads and saves are read-only to other users. Even files in public places like the shared application data folder (which is where I'm saving the files in question).
I'm lucky I found this before the 'vista-compatible' release. Vista hides the problem by redirecting non-admin writes and future reads to a sortof 'virtual' folder. But the next update may replace the file, and the non-admin program will still go to the virtual folder and use the old file.
As the admin user, how do I allow other users full control of files I write in vb6?
The way I do this is to make it an Installer responsibility.
Use VSI 1.1 to create an Installer MSI for your application. Create an application data folder under CommonAppDataFolder.
As a post-build step run a script to perform the following:
Set the MSI database for a per-machine installation: Property table, row with ALLUSERS set to 1.
In the Directory table, locate the entry for CommonAppDataFolder and obtain its directory Index. Use this Index to query the Directory table for an entry where CommonAppDataFolder is the parent and obtain its Index (this is your app data subfolder).
Look in the File table to obtain the component Index of your program.
Create the CreateFolder table in the database if it isn't present. Add a row to CreateFolder for the desired application subdirectory by its Index, tying it to your program's component Index.
Create the LockPermissions table if it isn't present. Insert a new LockPermissions row for your application data subdirectory, giving it FILE_ALL_ACCESS for Everyone.
That's about it.
You can do it this way, or use VSI 1.1 and then edit the MSI using Orca, or probably by using a 3rd party MSI authoring tool these entries will be settable via its GUI and can be saved in the Installer project. I just use a small WSH script I run after each VSI 1.1 build.
AFAIK this is the recommended way of accomplishing such things according to Windows application guidelines. If your needs are fancier you might use multiple subdirectories or sub-subdirectories some allowing full access, some read-only, etc.
Your program can locate the folder using Shell Automation objects or by calling Shell32 as a standard DLL (using Declare Function or a TLB).
It's not necessarily who writes the file, but where they write it to. The program files folder and it's sub folders are read-only to all standard users by default. Try using the All Users Application Data folder instead.
This is a little tricky for VB6, since it was not at all designed with Vista in mind. Some of the relevant folders were re-named and there's no way I know to get vb6 to give you the exact folder you want short of using a "Declare Function" alias to call directly into the windows API.
So the easiest reliable way I know to find a suitable location is to use the %ALLUSERSPROFILE% environment variable. That returns "C:\Documents and Settings\All Users" by default on XP and "C:\ProgramData" by default on Vista. From there you can look for an "Application Data" folder. It won't be there and you don't need it on Vista, but creating one if it doesn't exist won't hurt anything. That gives you a consistent folder structure on both systems from which you can create a sub folder for your app to use as a work space.
And one final note: this isn't a new change for Vista. Program Files folders have always been read-only to standard users by default. XP worked the same way. It's just that so many people run as administrators in XP you might be able to get away with it.
I have an automatic update system that replaces my existing program files on reboot. (Suffice to say, it's a very complicated program with many drivers, services, and user level modules. There really is no other way. Trust me.)
The function MoveFileEx is used with MOVEFILE_DELAY_UNTIL_REBOOT to setup this file replacement. I'm finding that it works just fine, normally. However, if the source and target files are on different drives, the target is deleted but the source is not moved. The result is that when the user installs the software on a drive different from the system partition, an update deletes the product file rather than update them.
Now, I see in the documentation for MoveFileEx that MOVEFILE_COPY_ALLOWED should be used when moving a file from one volume to another. But it also says that flag cannot be used with MOVEFILE_DELAY_UNTIL_REBOOT.
Q: How can I move a file on reboot, overwriting an existing file, when the source and the target are not on the same volume?
Why don't you just copy the files to the drive where the user installed your program?
As far as I see there is no direct way to do what you want relying only on this function.
Finding writable location on the same drive might be a problem on Vista, but you mention you have services - if they run with LocalSystem privilleges have them write the new files.
One other simple update mechanism that I have used ( not working for drivers though) is to have dedicated update program - kill/end everything, let the update program do its work and start everything up again.
