I wanted to install Oracle Instant Client On Windows for my laptop, a 32 bit system running Windows 7. I went to the Instant Client Downloads for Microsoft Windows (32-bit) and downloaded two zip files, instantclient-basic-nt-22.214.171.124.0.zip and instantclient-sqlplus-nt-126.96.36.199.0.zip. I unzipped them under the same directory. When I ran sqlplus, nothing happened.
$ $ sqlplus email@example.com:1521/xe $
Under the directory that I unzipped the downloaded files, I found a number of executable file such as adrci.exe in addition to sqlplus.exe. I ran adrci.exe and got the following error message.
$adric.exe "error while loading shared libraries: MSVCR100.dll"After doing some research about MSVCR100.dll on the internet, I went to Microsoft Download Center: Microsoft Visual C++ 2010 Redistributable Package (x86). Once I downloaded and install the package, I can run sqlplus and connect to the database server without issue.
