Excuse me, master, I have a software installed on my computer, but now there is no main file

This is an easy question to deal with. Use Windows Optimizer. One of the features of Windows Optimizer is the intelligent uninstallation of the software (when uninstalling, it will check all the files and registry entries related to this program), and it will prompt you whether to back up for later recovery before uninstalling.

Just right. After you've backed it up, copy the backup to your new computer and restore it with Optimizer. (The downside is if the software is large.)

It is recommended not to use it, then it is better to reinstall it, it is slow)

Of course, it is recommended that you check whether the software you installed is green? Or it doesn't have anything to do with the registry. As long as it has nothing to do with the registry. Directly put the program installation folder (that's where it is installed. Copy it to your new computer.

Use ghost to put the c drive ghost

Then install the ghost file directly to the new machine.

I've tried it several times.

It was a success. Of course, there will be a chance of failure.

There is no such software

You copy the main file, export the registration information of the software in the registry, and install it on your current computer, and it should work

Some of the paid software will not work on other machines

You're going to change the computer, you want this software, you have to have the main installer of this software, if you just copy your installation file, it's useless, because when installing a file, he will write something into the registry and system32 in it, so what is your software, and then you can search in it, and re-** the main installer of this software to the computer.

It depends on what kind of software it is, and if you have a database in the machine, you can't copy it.

You can compress it and drag it with a USB stick to try it.

Won't you get the next one again?

Summary. Hello pro Solution 1:

You have to set it on to see it.

Open with: Tools - Folder Options - View - Hide protected OS files (recommended), this option unchecks. Then select Show all files and folders.

Then you can find what you want in the C drive, which is hidden by default.

Solution 2:

Microsoft runs regedit to open the registry; schedule, there will be no restart, delete directly, here you will see that there are keys starting with i- setup; taskcache\currentversion\asus];tree, find [hkey local machine, exit the registry; software\windows nt\。

What should I do if the software is installed and there is no folder?

Dear hello, what kind of software is it?

360 compression.

Hello Pro Solution 1: You want to set it on to see it. Open with:

Tools --Folder Options --View--Hide Protected OS Files (recommended), uncheck this option. Then select Show all files and folders. Then you can find what you want in the C drive, this default is hidden solution 2:

Could it be caused by an imperfect software uninstaller or a user's direct deletion of the program installation directory?

Workaround: This can resolve the failure by attempting manual deletion. Directly click the "Start--Run--Run Input Regedit" command with the mouse, so that the registry dialog box can be opened, and the mouse will be located in order to hkey local machine software Microsoft Windows CurrentVersion Run.

Find the file line in the window on the right of the item, right-click the mouse, and delete the file directly.

The directory path is too long.

As shown in the figure below, this file can't be found, because the directory path is too long, windows can't recognize such a long directory, first of all, the parent directory of this directory is already the temporary cache directory of windows, and then a cache directory of the compressed package and then set the cache directory of the next compressed package, the directory path is too long, causing windows to be unable to recognize at all, so the prompt system can not find the specified file.

Extract the archive from the archive and open the file in it so that no error will be prompted.

Changing the temporary cache directory of the system will temporarily cache the directory.

Right-click My Computer -- Advanced -- Environment Variables.

You can change the same directory or a different directory, but don't use the root directory, use the root directory, it will cause a lot of temporary cache files, which is very messy.

Don't change the system environment variables lightly, remember.

In this way, when unpacking the nested package, the path will not become particularly long, and the error message will be solved.

The last problem that cannot be identified is that the Chinese directory cannot be recognized by garbled characters, and the solution is solved.

You can change the installed directory to Desktop, or change all Chinese directories to simple pinyin.

Desktop This Chinese directory is recognized as desktop, which is actually an English directory.

The end file is missing.

Some software, such as a private server login, has a certain potential virus, and is automatically blocked and deleted by various security software, depending on whether the user is sure that there is no virus harmful characteristics.

So you can make sure that this file is not present with the target directory.

First of all, we must figure out how the general software is installed, it is not only to copy the folder (maybe it is to extract and copy) to a folder on your machine, and then to carry out a system "registration", in fact, the registry of the system has been changed, so the system will know the existence of this software, including; What common "tools" does it use (so that you don't have to make your own copy of each software design), it may have to go to the registry to read some data when it runs, it creates some files when it runs, it needs to associate with its program, where to find it, and so on.

Then you don't need this software anymore, you can't just delete that folder, and at the same time, you have to cancel all the items it registered at the beginning, which is often called "uninstalling".

If for some reason, there is no normal complete uninstallation (even the software itself uninstall the program is improperly designed), the least harmful thing is that some things become garbage - it takes up part of the space and affects the speed of reading and writing other programs in the system, generally like you belong to one kind now, and there are many different abnormal prompts that may occur, and the harm is serious and the system can hardly run normally.

Of course, it is also possible that other software or even viruses may cause confusion in some items of the registry. In short, you can't generalize just by saying this one prompt phenomenon.

I don't know if you understand something about this?

The system determines whether the software is installed or not to see if your folder is still there.

Because there are so many folders, it doesn't know which folder corresponds to which software.

The system records whether the non-green version of the software is installed or not depends on the registry.

The registry will record the name of one of your software, the installation path, etc.

Press Ctrl+R on the left side, type regedit to confirm, and this one opens the registry.

In this case, you want to find the folder, open the exe file directly, or reinstall it.

Maybe the deletion is not complete.
