When I run the installation for Essential Suite, another installer is launched instead. Why?

Another installer launched when install Syncfusion Essential Suite

Our install packages are zipped up into a WinZip self-extracting executable file. When the "Installer" button is pressed, the packaged files are extracted to a temporary folder.

After the files are extracted, the executable attempts to launch the extracted "Installer.exe". If there is a "Installer.exe" file in the same directory as the self-extracting executable, then this installer program is run instead. It may also be possible that there is a "Installer.exe" file in another temporary folder. To get around this, make sure that there is no conflicting installer file in the directory.
