Acrobat DC installation: Inexisting path and other flaws

The installation program for Acrobat DC asks for inexisting path C:\Program Files (x86)\Adobe\\Setup Files\{AC76BA86-7AD7-FFFF-7B44-AB0000000001}\ for AcroRead.msi batch! You see, there couldn't be even such thing as double slash for any address (path) on a hard disk but, nevertheless, it is always required ! Any correct address for AcroRead.msi is ignored by the installer as ingenuine for it. Any ealier version to install is ignored by their installers as obsolete for my PC. Having Reader XI earlier soon required regular updates but no updates succeeded to proceed due to mistake with an address. Uninstallation, in its turn, has been blocked by the absence of admisitrative rights to access until I used an Unlocker! What is going with your Reader updates ind installations? And you try to save individual users demand with these user unfriendly peculiarities? I need no Acrobat Reader version unless to fill in any PDF application form, if I can't install even ealier versions now. I'm neither a programmer, nor a hacker, just an ordinary user so you wouldn't care ever? Pls notice: readerdc_ru_xa_cra_install.exe - isn't flawless distributive at all.
